Old Rock Baptist Church
Somerset, Atascosa County, Texas
Marker Inscription
Organized as Medina Baptist Church in April 1857 at Mann's Crossing, near Macdona. Until 1866, when members built an arbor here near Old Somerset, the services were held in homes or in a schoolhouse. Site for meetinghouse and cemetery (2.5 acres here) was bought for ten dollars in 1867 by committeemen F. M. Avent, Elisha A. Briggs, and W. D. Johnson on behalf of Medina Church. This committee also drew the plans; Briggs, a settler from Massachusetts and a stonemason, did much of the construction. Worship began here in 1869 as soon as house had roof and walls--although door and window spaces were empty and there was no floor except bare ground. In those early days, four ordained ministers took turns as unpaid pastors. Avent was clerk and sexton. Medina Church membership was racially integrated. Some of the Negro members lie buried in honored graves in the cemetery. In 1892 Medina Church relocated at Bexar. Cemetery maintenance was continued here; "Old Rock" was used at times for funerals or worship. In 1921, after local petroleum discoveries, Grayburg Oil Company and some of its employees helped renovate the meetinghouse. Congregation renamed itself for the Old Rock Church and regular worship has continued here ever since. Recorded Texas Historic Landmark - 1971

The Story
Organized in 1857 as Medina Baptist Church at Mann's Crossing, this congregation worshiped in homes and a schoolhouse before building a stone meetinghouse here in 1867–69, much of it laid by Massachusetts stonemason Elisha Briggs. In its early years four ordained ministers took unpaid turns in the pulpit, and the church's membership was racially integrated, with some of its Black members buried in honored graves in the cemetery. After the congregation relocated in 1892, the beloved "Old Rock" building was renovated in 1921 with help from a local oil company and renamed for the church.
Why it matters
A rare integrated frontier congregation, it preserves a chapter of shared worship across racial lines in nineteenth-century Texas.
The story behind this marker
AI contextThe era
When this congregation first gathered in the spring of 1857, the land around Mann's Crossing was still the raw edge of settled Texas. The state had joined the Union barely a decade before, and the country that would become Atascosa and Medina county land was thinly settled ranching and farming country, where a schoolhouse or somebody's front room often had to double as a house of worship. There were few church buildings this far out, and fewer paid ministers, so faith traveled with the settlers and put down roots wherever a handful of families could meet.
The years that shaped this church straddle one of the great fault lines in American life. It was founded in the last years before the Civil War, and it built its first real home here in 1866–69, in the raw aftermath of that war, during the era of Reconstruction. That timing matters: a stone meetinghouse rising on newly purchased ground in these years was an act of hope in an unsettled and often bitter time.
This was also frontier South Texas, a landscape of open country and small crossings where the arrival of the railroad, the discovery of minerals, or the shifting of a settlement could make or unmake a community within a generation. The church's long life — organized in one place, built in another, relocated, and revived — mirrors how fluid and improvised community life was on this frontier.
People & events
The story really begins with three committeemen — F. M. Avent, Elisha A. Briggs, and W. D. Johnson — who in 1867 bought two and a half acres here for ten dollars, land meant to serve both the living and the dead. They didn't just buy it; they planned the building themselves. It was a congregation doing everything with its own hands.
One of those hands belonged to Elisha Briggs, a settler who had come all the way from Massachusetts and worked as a stonemason. Much of the building's construction was his labor, stone by stone. Picture worship beginning here in 1869 the moment the walls and roof were up — the doorways and windows still open to the weather, no floor but the bare earth underfoot. Four ordained ministers took turns in that unfinished room, none of them paid, while Avent served as both clerk and sexton, keeping the records and tending the ground.
The congregation's membership was racially integrated, and the marker records that some of its Black members lie in honored graves in the cemetery — an unusual note of shared worship for its time and place. Decades later, after the church body had relocated in 1892, a new chapter opened: local oil discoveries brought the Grayburg Oil Company and its workers, who in 1921 helped renovate the old stone building. The congregation renamed itself for the beloved "Old Rock," and worship has continued here ever since.
Its place in the American story
Small frontier churches like this one are where the largest American stories were actually lived out. The national arc from the eve of the Civil War through Reconstruction is usually told through battles and legislatures, but it was also felt in whether neighbors of different races could kneel together in a half-finished room — and here, for a time, they did. That makes this quiet stone building a witness to a possibility that much of the country struggled to realize.
It also captures a distinctly American pattern of self-reliance and faith. There was no distant authority building this church; there were committeemen drawing plans, a mason from Massachusetts laying stone, and unpaid preachers rotating through the pulpit. Multiply that scene across thousands of communities and you have the real texture of how religion and community took root across the expanding country.
And its revival tells another national story — the way oil transformed Texas in the twentieth century. That a petroleum company and its employees helped save a nineteenth-century meetinghouse ties this humble site to the larger transformation of a rural frontier into part of the modern American economy.
If you visit
This is a place to slow down and read the landscape rather than rush a tour. Stand near the old stone building and remember that its walls were laid by hand, and that the earliest worshippers stood on bare ground with the weather coming through empty window frames. The stonework itself is the artifact — look at how it was fitted, and think of the mason who carried that craft here from New England.
Give time to the cemetery. Two and a half acres were set aside here for graves as well as worship, and among the pioneers rest members of an integrated congregation, some of them Black members laid in honored graves. Walking those rows is the most direct way to feel the church's history of shared worship across the color line.
On a road trip through South Texas, a stop like this pairs naturally with the wide, open ranching country around it — a reminder that community out here was built one crossing, one schoolhouse, one meetinghouse at a time. It's an unhurried, contemplative stop, best appreciated by anyone curious about how faith and neighborliness survived on the frontier.

Ihnken Family Cemetery
Castroville, TX
Early Castroville colonists—Dutch and German immigrants who arrived on Henri Castro's ships in the 1840s—rest in this small family plot, where Marie Becker Ihnken was buried in 1847. Her son Gerhard, a leading citizen, farmed vast lands and ran a sawmill, store, and orchard, and is credited with bringing the area's first reaper and binder. One of Medina County's oldest cemeteries, it holds eight marked Ihnken graves and, by tradition, a freedman who worked for the family; it has stayed inactive since 1950 to protect unmarked graves.
Pleasanton School Integration
Pleasanton, TX
Pleasanton had educated its African American children at the Abraham Lincoln School since 1913, and by the mid-1950s Black and white students were already practicing and playing sports together. When the Lincoln School proved inadequate and Texas's House Bill 65 required a community petition and vote before integration, Pleasanton's residents supplied both, approving the measure 343 to 88 on October 26, 1957. Days later nine Black students entered the new high school before assembled press, welcomed by their classmates in a transition that recorded no violence.
Westside Black Enclaves
San Antonio, TX
San Antonio's Black history reaches back to its earliest days, from presidial soldiers of African ancestry to the North African Berber heritage of the Canary Islanders. By 1885 the city's Second Ward, west of the San Antonio River, was home to a substantial Black community anchored by institutions like St. James AME Church—begun in 1868 in a former soap factory—and the West End Baptist Church. Community leaders such as Ella Austin, who opened an orphans' home nearby in 1890, and gathering places for literary societies and glee clubs gave the neighborhood civic and cultural life before it later transformed into a Latino cultural center.
St. Philip's College (original site)
San Antonio, TX
In 1898, at a time when educational opportunities for Black Texans were painfully scarce, an Episcopal bishop opened a Saturday sewing class for African American girls on this site in San Antonio. That modest class grew into St. Philip's — an industrial and normal school shaped for more than half a century by Artemisia Bowden, a Black educator from Georgia who arrived in 1902 and stayed 52 years, steering it from a handful of students toward an accredited junior college. Absorbed into public control in 1942 and racially integrated in 1955, it endured as one of the nation's historically Black colleges.
