Captain Charles Schreiner

Kerrville, TX

Born in France in 1838, Charles Schreiner emigrated as a boy, rode with the Texas Rangers, and fought for the Confederacy before opening a Kerrville general store in 1869. From that counter he built an empire — banking, ranching, and the marketing of wool and mohair through one of Texas's first such warehouses — until by 1900 he owned some 600,000 acres. A noted philanthropist, he founded the Schreiner Institute that still bears his name.

Captain George M. Levingston

Orange, TX

Orange, Texas sat where the Sabine River meets the Gulf, and its economy floated on the boats built along that water. George M. Levingston, a licensed river captain and son of an early shipbuilder, turned decades of local shipyard experience into the Levingston Shipbuilding Company in 1933, growing it into a major Gulf Coast operation. He also gave time to public life, serving on the Orange City Council in the 1920s.

Captain Hanson Gregory

Rockport, ME

In the seafaring town of Rockport on the Maine coast, local lore credits sea captain Hanson Gregory with punching the first hole in a fried doughnut in 1847, supposedly so the dense center would finally cook through. The claim is celebrated but contested, one of many folk origin stories for the ring-shaped treat. This monument keeps Rockport's tie to the legend alive.

Captain James W. Magoffin, Major Simeon Hart

El Paso, TX

Kentucky-born trader James Magoffin and New York-born miller Simeon Hart both built fortunes in the El Paso borderlands—Magoffin from a trading post at Magoffinsville and his deep contacts in Mexico, Hart from a mill grinding a hundred barrels of flour a day. When the Civil War came, both threw their commercial networks behind the Confederacy, funneling supplies to the 1861–62 Arizona–New Mexico campaign and trading Southern cotton for war goods through Mexico and Europe. Hart's arrangements even helped thwart a planned Union thrust across the Rio Grande in 1863.

Captain Joe Byrd Cemetery

Huntsville, TX

A few blocks from Texas's first prison — the 1848 Huntsville Penitentiary — the Captain Joe Byrd Cemetery holds more than 3,000 people who died in state custody, the earliest laid to rest in the 1850s. For a century the graves went largely unrecorded until assistant warden Joe Byrd cleared the overgrown ground and located over 900 of them, lending the cemetery his name. It remains the only active burial place in Texas for inmates whose bodies go unclaimed.

Captain N. A. Birge House

Sherman, TX

Connecticut-born Noble Allan Birge came to Texas before the Civil War, served as Marion County's first sheriff and then as a Confederate captain, and afterward became a leading cotton merchant. He moved his family to Grayson County in 1874, and after the great Sherman tornado destroyed his earlier home, he built this exuberant Queen Anne and classical revival house in 1896, where the Birge family remained until 1969.

Carbon County

Jim Thorpe, PA · est. 1982

Carbon County, formed in 1843 from Northampton and Monroe, was named outright for the element at the heart of its wealth: the rich anthracite coal beds that fueled America's industrial rise. Its seat began life as Mauch Chunk, a booming coal-shipping town on the Lehigh, and in 1954 took the name Jim Thorpe to honor the great Native American athlete, whose remains were brought there. The renaming stitched a legendary Olympian's memory to a hard-coal town.

Carbondale

Carbondale, PA · est. 1947

In 1822 the Wurts brothers of Philadelphia gambled on a hard, hard-to-burn rock that most people still doubted could be sold as fuel: anthracite coal. To reach the buried seams of this Lackawanna Valley town, they opened one of the first true underground mines in the region here in June 1831, and to carry the coal to market they helped pioneer the Delaware & Hudson gravity railroad. The mining boom grew so fast that by 1851 the settlement was chartered as a city — reputedly the first in the anthracite fields.

Carbondale

Carbondale, PA · est. 1947

In the hard-coal country of northeastern Pennsylvania, the Wurts brothers gambled that the black rock underfoot could power a nation, laying out this settlement in 1822 to tap the region's anthracite. Here in June 1831 the first underground mine in the area was opened, a turning point from surface digging to deep shafts that would define Pennsylvania coal for a century. Growth came fast enough that the community won a city charter in 1851 — one of the earliest in the anthracite fields.

Carbondale

Carbondale, PA · est. 1947

In 1822 the Wurts brothers, gambling on the hard, clean-burning anthracite locked in these northeastern Pennsylvania hills, laid out the settlement that would become Carbondale. Nine years later, in June 1831, the region's first underground anthracite mine was opened here, driving shafts into the earth rather than merely stripping coal from the surface. The venture helped spawn the Delaware & Hudson enterprise that hauled the coal to distant markets, and by 1851 the fast-growing town had earned a city charter.

Carey Lake-Boggy Creek Oil Field

Jacksonville, TX

Cherokee County's first commercial oil field was discovered near Carey Lake and Boggy Creek by the Humble Oil and Refining Company in 1927. A well at the northeast corner of Carey Lake revealed the telling link between oil deposits and underground salt domes, and Humble pioneered recovery methods here, using seamless tubing and oil-gas ratios that became industry standards. Production continued into the 1950s.

Cargill-Wright Company Building

Columbus, GA

As Columbus grew into a Chattahoochee River industrial city, this 1902 building housed a succession of food producers — candy makers, syrup refiners, and a hosiery mill — and later the Sol Loeb wholesale grocery firm. Loeb was among the first customers of the Wrigley chewing-gum company and a founding member of the local telephone exchange.

Carl and Hilda Biehl House

Galveston, TX

Two years after the 1900 hurricane leveled much of Galveston, German immigrant Carl Christian Biehl arrived and built a shipping firm that served the island in the years before Houston's port rose to prominence. In 1915 he bought a storm-damaged property at 1416 Broadway and replaced it with a brick-and-concrete Classical Revival home, designed by architect Anton F. Korn, Jr. and engineered to withstand the Gulf's storms. The house stayed in the Biehl family for nearly a century, cared for at the last by their daughter, the artist Margaret 'Sis' Biehl.

Carl G. Fisher and Alfredo Gonzalez

Miami Beach, FL · est. 2018

A 1961 exile from Cuba, Alfredo Gonzalez, Sr. worked several jobs before opening a small Cuban luncheonette in Miami Beach and, later, the beloved David's Café, which he ran for decades. His success let him support the city's churches and champion its elderly, and he restored several historic properties, including a bungalow built by Carl Fisher in 1914. In 2018 the City of Miami Beach dedicated this marker to honor his family's story.

Carl G. Fisher, Lincoln Road, and Morris Lapidus

Miami Beach, FL · est. 2020

Carl Fisher laid out Lincoln Road in 1914 as Miami Beach's "Fifth Avenue of the South," and it flourished as a fashionable shopping street. When traffic and competition threatened it in the late 1950s, merchants hired architect Morris Lapidus, who in 1960 reimagined it as a landscaped pedestrian promenade with his signature "piano key" paving, planting beds, and follies. It became one of the first pedestrianized thoroughfares in the United States and the oldest pedestrian mall in Florida.

Carl Wilhelm August Groos House

San Antonio, TX

Carl Wilhelm August Groos left Germany for Texas in 1848 and became a founder of the Groos National Bank in San Antonio. In 1880 he built this limestone Victorian home, designed by the noted architect Alfred Giles, where his descendants lived until 1948. The San Antonio Girl Scouts acquired the house in 1957.

Carlin

Carlin, NV

Carlin, the oldest town in Elko County, was laid out by the Central Pacific in December 1868 at a meadow long favored as a stopping place by emigrant wagon trains, where crews built a roundhouse and shops and named the town for Union general William Passmore Carlin. Through the 1870s and 1880s it vied with neighboring towns for the freighting business of the surrounding mining camps, and for decades it served as an important icing station for refrigerator cars. In 1965 it became the shipping point for the nearby Carlin gold mine, one of the largest in the country, and remains a working railroad division point.

Carlisle Iron Works

South Middleton Township, PA · est. 1947

Established around 1762, the Carlisle Iron Works turned the abundant ore, timber, and waterpower of the Cumberland Valley into iron during the colonial and early national periods. After 1781 it passed to Michael Ege, one of the region's most prominent ironmasters, whose family built a small empire of furnaces and forges. The ruins of its charcoal furnace still stand as a reminder of that early industry.

Carlson

Manor, TX

Brothers Pete and John Carlson, Swedish immigrants who came to America in 1869, settled here in 1881 and helped found a small cotton-farming community. Pete opened the area's first store and John ran the cotton gin, and at its height in the early 20th century Carlson supported family farms, a school, a band hall, and a community club. As ownership changed hands the gin and store took new names, but the town's life turned on cotton.

Carnegie Hero Fund Commission

Springdale, PA · est. 1995

When an explosion ripped through the nearby Harwick Mine on January 25, 1904, killing 181 workers, would-be rescuers gave their own lives trying to reach the trapped men. Their courage moved steel magnate Andrew Carnegie, who that April established the Pittsburgh-based Carnegie Hero Fund Commission to recognize ordinary people who risk everything to save others. The commission still awards the Carnegie Medal across the United States and Canada, and Carnegie went on to found ten similar funds in Europe.

Carnegie Public Library Dome

Wabash, IN

Between the 1880s and the 1920s, steel magnate Andrew Carnegie's philanthropy funded roughly 2,500 public libraries, and Wabash, Indiana, was among the towns that received one. Its dome crowns a classic Beaux-Arts library building of the kind that brought free reading rooms to small-town America for the first time. These libraries were designed to look like temples of learning — dignified civic anchors meant to lift working communities through knowledge.

Caroline Gilbert Hinchee House

Beaumont, TX

Caroline "Carrie" Gilbert Hinchee (1863–1913), a Beaumont-born artist and teacher trained at leading institutions, married businessman Martin Luther Hinchee in 1900 and drew wealth from her family's Gilbert Oil Company. In 1906 she built this elaborate Queen Anne residence, designed by architect Henry C. Mauer, with a tiled roof, wraparound veranda, stained glass, a glass conservatory, and one of the city's first residential elevators. A civic leader and DAR charter member, she made the home a symbol of turn-of-the-century Beaumont.

Carousel

Arlington, TX

This 1966 state marker recalls the carousel's heyday in Texas, when traveling shows and carnivals brought the ornate, horse-drawn rides from town to town. The arrival of a carousel was a genuine event, its calliope music helping celebrate townsite openings, finished railroads, and boom-town milestones. It commemorates a shared piece of popular culture rather than a single site.

Carpenters Bluff Bridge

Denison, TX

Completed in 1910, this span across the Red River was first built as a railroad bridge for the Missouri, Oklahoma and Gulf Line, which needed a Grayson County connection to win better freight rates for Oklahoma coal. Engineered to survive the kind of flood that had wrecked area bridges in 1908, it also carried a "wagon shelf" so toll-paying pedestrians, riders, and horse-drawn vehicles could cross alongside the trains. After the railway ceased Texas operations in 1965, the counties converted it to a free public roadway that still links Texas and Oklahoma.

Carr Chevrolet Company

Beaverton, OR

This plaque honors the Carr Chevrolet Company, described as the oldest dealership in Washington County, Oregon, founded by Guy C. Carr, who established his automobile agency in 1918. The early 20th century saw automobiles transform American life, and local dealerships like Carr's brought the age of the car to towns across the country. The plaque was presented in 1971 by past and present employees.

Carr-Taliaferro House

Sherman, TX

Prosperous farmer and landowner Richard Bell Carr and his wife Susan moved into Sherman from the surrounding countryside and hired the respected contractor J. R. Barrow to design this dignified residence in 1902. Their daughter Susiebel was married in its front parlor in 1915, and the couple went on to inherit and enlarge the home. It was recognized as a Recorded Texas Historic Landmark in 1978.

Carrere Memorial

New York, NY

John Merven Carrère was one of the most influential American architects of the Gilded Age, a founding partner of the celebrated firm Carrère & Hastings, which shaped the Beaux-Arts style that defined turn-of-the-century civic America. With his partner Thomas Hastings he designed landmarks such as the New York Public Library's main branch, bringing a grand European classicism to the nation's growing cities. Carrère died in 1911 from injuries in an automobile accident, and in 1919 Hastings honored his late partner with this memorial, a personal tribute from one half of a legendary architectural partnership to the other.

Carson and Colorado Railroad Freight Depot

Mineral County, NV

This freight depot was the first railroad building erected in Hawthorne, a surviving remnant of the narrow-gauge Carson and Colorado Railroad that pushed south from Mound House in 1881. Railroad officials laid out the town in the desert and auctioned its first lots that April. The line was later extended into California's Owens Valley, but Hawthorne's rail service ended when the town was bypassed in 1905, and the depot went on to serve as a store, a bar and restaurant, and finally an Elks Lodge hall.

Carson County

Panhandle, TX

Carved out of the vast Texas Panhandle in the years after the Civil War, Carson County was created in 1876 and formally organized in 1888 as ranchers and railroad promoters pushed into the high plains. It took the name of Samuel Price Carson, who served as Secretary of State for the young Republic of Texas. The town of Panhandle became the county seat and, though it lost the great rail junction it was promised to nearby Amarillo, it endured as one of the region's early enduring towns and an early player in the oil and gas boom.

Carson County

Panhandle, TX

Carson County was created on August 21, 1876, from earlier Young and Bexar territories and organized in 1888 as settlers spread across the Texas Panhandle. It honors Samuel P. Carson (1798–1840), a statesman of both the United States and the Republic of Texas. Wheat farming and later oil and gas made the high-plains county prosperous, with the town of Panhandle as its seat.

Carson Valley

Douglas County, NV

The broad, cultivated Carson Valley below began as a ribbon of natural meadow where California-bound 49'ers rested their stock and bought vegetables from the Mormon Station settlers. After the 1858 discovery of the Comstock Lode, farmers extended the meadows by irrigation to feed the miners of Virginia City, and from 1870 German, Danish, and Swiss immigrants enlarged the fields further to supply booming camps like Bodie, Tonopah, and Goldfield. Sound range and farming practices have kept it among Nevada's finest agricultural regions.

Cartersville

Springtown, TX

Founded in 1866 by a judge and two partners, Cartersville grew into a bustling community with two main streets, a school, two churches, and mills and gins serving area farmers. A post office opened in 1867 and the town was renamed Carter in 1888. By the early 1900s it had begun to fade, and little remains today.

Casa de Palmas

McAllen, TX

Where a city park once kept antelope, javelina, and deer, McAllen's boosters built the Casa de Palmas in 1918—a three-story, red-tile-roofed hotel with twin towers around a central patio, meant to be the young town's business and social hub. It sheltered residents through the devastating 1919 hurricane and, after a 1973 fire, was rebuilt faithfully in its original Spanish style.

Casa Ortiz

Laredo, TX

Casa Ortiz stands on land granted by the King of Spain to Don José Reyes Ortiz, a merchant who served as a go-between for trade linking Mexico and Texas. The house sheltered five generations of the Ortiz family and was recorded as a Texas Historic Landmark in 1964. Its story reaches back to Laredo's Spanish colonial origins, when the town was a frontier settlement on the northern edge of New Spain.

Casey Jones

Memphis, TN

On the night of April 29, 1900, engineer John Luther 'Casey' Jones took out Illinois Central engine 382 to pull the fast passenger train known as the Cannonball. Racing to make up lost time, he came upon a blocked switch at Vaughan, Mississippi in the early morning and stayed at his throttle to slow the train, dying in the wreck while his passengers survived. His sacrifice made him one of the great folk heroes of the American railroad.

Cashier's House

Erie, PA · est. 1980

Completed in 1839, the Cashier's House was built as an elegant residence for the officer who managed a branch of the U.S. Bank of Pennsylvania in Erie. The bank stood in the turbulent final years of America's early banking wars, when the Second Bank of the United States had lost its federal charter and reorganized under state law. Its refined Greek Revival architecture reflects the prosperity and ambition of a growing Great Lakes port town.

Cashion School

Wichita Falls, TX

Wichita County built this one-room schoolhouse in 1902 on land donated by H.F. Knippenberg, naming it for county commissioner T.J. Cashion; it opened with a single teacher and twelve students. The 1918 discovery of oil at nearby Burkburnett sent enrollment soaring, and the school expanded through the 1920s to a peak of 286 students. When oil production fell in the mid-1930s the community declined with it, and the school closed by 1943.

Cassaday Grey Granite Company Office Building

Llano, TX

Businessman Tye Yates Hill raised this building in 1919 as the office of the Cassaday Grey Granite Company, named for the landowner whose ground held a prized vein of grey stone. Its mission revival styling—an "Alamotif" parapet and rounded arches—dressed up the workaday business of quarrying at the height of Llano's granite boom. The 1929 stock market crash wiped out Hill's granite venture, and the building passed to other uses; since 1967 a succession of bakeries has filled its rooms. It was named a Recorded Texas Historic Landmark in 1993.

Casterline Fish Company

Fulton, TX

During the 1930s Cecil Weber Casterline opened a Fulton "fish house" on the Gulf, buying oysters, shrimp, and fish from local boats, packing the catch in barrel ice, and shipping it inland by rail to San Antonio and beyond. With his father Frank he bought the harbor property in 1944, and the family, later joined by brother Leslie after World War II, built their own fleet of boats named for relatives. For some eighty years Casterline Fish Company was a mainstay of the Coastal Bend seafood trade before its 2015 sale to Prestige Oysters.

Catarina Hotel

Catarina, TX

Catarina rose in the 1920s around the headquarters of the Sinton-Taft (later Taft-Catarina) Ranch, which Kansas businessmen bought for development and sold off to eager buyers. By 1928 the town claimed some 2,500 residents and a full complement of businesses, including this Spanish Eclectic hotel built in 1925–26 with tile roofs, mission detailing, cast stone, and a courtyard with a fish pond. The building once also held a bank, café, shops, and offices.

Cathalorri

Montgomery, TX

Built in 1854 for merchant R.S. Willis by craftsman J.E. Shelton, this antebellum Texas home was assembled with hand-planed siding and a pegged-and-morticed frame — the careful joinery of a pre-industrial builder. It was restored in 1965 by the Waldrop family, who named it "Cathalorri" for their two granddaughters. The house was recorded as a Texas Historic Landmark in 1966.

Cattle Drives from South Texas

Corpus Christi, TX

By 1840 tens of thousands of wild longhorns roamed the brush country between the Rio Grande and the Gulf, so plentiful they were nearly worthless to the Texans who owned them. Ranchers began trailing small herds toward distant markets — New Orleans, Missouri, Ohio, even California and Chicago — but the real boom came after the Civil War, when hungry Northern cities and advancing railroads finally made the long drives pay. Feeder trails near here fed the great Chisholm and Dodge City routes to the Kansas railheads, and by 1880 some four million head had gone up the trail.

Cattle Raisers Association Oak

Graham, TX

Under this oak near Graham in February 1877, forty cattlemen banded together to form the Cattle Raisers Association of Texas, choosing their first officers on the open range. In an era of unbranded strays, rustling, and the great trail drives, the group organized ranchers to protect their herds and their interests. By 1936 the association counted some 2,500 members.

Cayuga - Seneca Canal

City of Geneva, NY

In 1828, water flowing out of Seneca Lake christened the Cayuga–Seneca Canal, a Finger Lakes spur of New York's mighty Erie Canal system. The new waterway stitched the lakeside town of Geneva into a continuous route running east to the Hudson River and on to the Atlantic. For a region settled only a generation earlier, the canal turned isolated farms and mills into players in a national and global market.

CCC Camp Site

Madisonville, TX

Camp Sam Houston, opened near Madisonville in 1935, was a soil-conservation unit of the New Deal's Civilian Conservation Corps, giving work to 196 men in the depths of the Great Depression. Its members ranged across Madison and neighboring counties, teaching farmers and ranchers erosion control and pasture management within a 21-mile radius. The camp closed in 1941 as the nation turned toward war.

CCC Company 850

Mesquite, TX

During the Great Depression, farmer Hicks Jobson set aside eight acres near Mesquite so the Civilian Conservation Corps — one of Franklin Roosevelt's New Deal work-relief programs — could establish a camp. From June 1935, Company 850's 250 enrollees lived in a small city of barracks, a mess hall, and a bath house while working with more than 300 area farmers on soil conservation across 40,000 acres. Their terracing, fencing, check dams, and levees along the Trinity River continued until 1941, after which the land was donated to the local school district.

CCC Monument (stone fireplace and chimney)

Harris Township, PA

This stone fireplace and chimney are all that remain of a Civilian Conservation Corps camp, one of thousands that dotted the country during the Great Depression. Beginning in 1933, President Franklin Roosevelt's New Deal put unemployed young men to work here under the CCC — Company 361 at Camp S-62-PA — planting trees, fighting erosion, and building the trails, roads, and shelters of Pennsylvania's state forests and parks. The hand-laid stonework is a signature of CCC craftsmanship, meant to last long after the tents and barracks came down.

Cecil and Frances Brown House

Friendswood, TX

Designed by Houston architect Henry A. Stubee and built in 1938, this French eclectic house was the home of civic and business leader Cecil Brown and his wife Frances, both from pioneer Quaker families. Brown was prominent in the Gulf Coast fig industry that flourished from the 1920s to the 1950s and is credited with much of Friendswood's development. For years it was the only brick residence in the area.

Cecil B. DeMille

New York, NY

Filmmaker Cecil B. DeMille lived at this New York address from 1906 to 1913, in the years before he headed west to help invent Hollywood. In 1913 he directed 'The Squaw Man,' celebrated as the first feature-length film made in Hollywood, launching a career of some 70 pictures. Famed for lavish spectacles like 'The Ten Commandments,' DeMille became one of the defining showmen of American cinema.

Cedar Chopping in Central Texas

Austin, TX

After Texas won independence in 1836, settlers drawn by timber and Brushy Creek's water carved farms and ranches from the land that became Williamson County in 1848. Beyond cotton and livestock, families harvested the ashe juniper they called cedar—cutting fence posts, roof shingles, telephone poles, and charcoal, and shipping cedar rail ties once four rail lines crossed the county. The itinerant 'cedar choppers' who moved camp to camp, including one leased here in 1905–08, became a defining local trade well into the twentieth century.

Cedar Falls Mill

Randolph County, NC

Chartered in 1828 and opened in 1836, Cedar Falls was one of the early textile mills that harnessed the water power of the Deep River in Randolph County. Jonathan Worth — who would serve as North Carolina's governor from 1865 to 1868 — headed the enterprise, and during the Civil War the mill supplied cloth for the Confederate war effort.

Cedar Hill

Silver, TX

Stock-farming homesteaders settled the Cedar Hill area around 1890, naming it for a nearby cedar-covered rise and building a one-room school in 1891 near the cemetery that still remains. No town ever took hold — drought and hardship drove many families away by 1904, and the school closed after 1917. Three decades later an oil boom swept the county, and the once-emptied land came to sit within one of West Texas' largest oil fields.

Cedar Lake Salt Works

Brazoria vicinity, TX

Built in 1861–62, the Cedar Lake Salt Works supplied a resource the Confederacy could not do without — salt to preserve meat for its armies and civilians. In November 1862, Federal landing parties from Gulf ships raided the works, destroying buildings, kettles, and boilers and ruining stored salt. When they struck again the next day at a nearby plant, Texas cavalry and Moseley's Battery of the 7th Texas Artillery Battalion drove the raiders back to their boats.

Cedar Lawn

Galveston, TX

In 1926, as Galveston recovered from the great storm era and reinvented itself, the Moody family—one of the island's wealthiest business dynasties—created Cedar Lawn as a planned residential enclave for family members and company officers. Its designers deliberately broke from Galveston's rigid grid, weaving in a circle, semicircles, and a shared central garden, with houses turned inward for a sense of retreat. Deed restrictions, curated architecture in Tudor, Mediterranean, and Colonial Revival styles, and streets owned by the residents themselves made it one of the city's most distinctive neighborhoods, recognized on the National Register in 2002.

Cedar Mills

Brush Creek Township, OH

In the hills of Adams County, Ohio, Cedar Run once powered a small industrial world. The first mill here rose in 1811 to serve a nearby iron furnace, part of the charcoal-iron trade that dotted the Appalachian foothills before the furnace went cold in 1840. Milling continued when Fisher and Stewart raised a new grist mill in 1844, and a generation later its owners traded the fickle water wheel for a steam engine, its tall brick smokestack marking the arrival of a new industrial age.

Cedar Springs

Dallas, TX

Surveyed in the late 1830s during preparations for a military road, the Cedar Springs area drew Dr. John Cole and his family in 1843 under a Peters colony land grant. Cole built a home and store near the springs, and a small community with a distillery, flour mill, and grist mill grew up around them. After Dallas was chosen county seat in 1850 the town faded, later revived as the suburb of Oak Lawn and absorbed into Dallas between 1920 and 1940.

Cement City

Donora, PA · est. 1997

Built in 1916–17 to house workers at American Steel & Wire's Donora plant, Cement City was a planned community of 100 units in 80 Prairie-style buildings. Its buildings were poured in place from concrete — an experimental construction method meant to deliver durable, affordable company housing quickly. One of several such concrete communities across the country in that era, it endured to shelter generations of steelworkers' families and is now a National Register Historic District.

Central Artery Tunnel

Boston, MA

Boston's Central Artery/Tunnel Project — the "Big Dig" — buried the city's elevated highway underground and reconnected neighborhoods that concrete had severed. Begun in 1987 and running for well over a decade, it was one of the largest and most complex public-works projects in American history. This plaque honors the more than 15,000 people who designed, managed, and built it, and especially those who died in its construction.

Central Baptist Church

Burkburnett, TX

In 1924 fourteen people met at Bradley's Corner Community Center to organize a missionary Baptist church, soon relocating to the nearby oil boomtown of Thrift and building with donated lumber. As members moved into Burkburnett, the congregation carried its building into town in 1952 and, after further growth, renamed itself Central Baptist Church in 1961 to reflect its new role as a city church. It continues to serve the Burkburnett community.

Central Christian Church

Texarkana, TX

Organized in 1883 under the Rev. J. C. Mason, the Central Christian Church congregation raised this Tudor Gothic Revival sanctuary in 1932 under the supervision of architect and church member E. C. Seibert, who set the brick in a distinctive decorative pattern. Cast-stone details, pointed-arch windows, and a pointed-arch arcade linking sanctuary and education wing mark its careful design. It remains a landmark of Texarkana's ecclesiastical architecture.
