Bowen's Island

San Antonio, Bexar County, Texas

Marker Inscription

This tract of land is a natural peninsula in the San Antonio River. It once was bounded by the river on three sides and on the fourth by the Concepcion Acequia. In 1845 John Bowen, a native of Philadelphia, bought the property from Maria Josefa Rodriguez de Yturri for $300. Bowen and his wife, Mary Elizabeth, built a seven-room home on the island for their family of six children. Here they planted fruit trees and gravevines. On the east bank of the river, they built a waterwheel to irrigate their truck farm. During the 1840s and 1850s John Bowen served San Antonio as United States postmaster and city treasurer. He was a staunch Unionist and, according to family tradition, protected fugitive slaves. John Bowen died on the island in 1867 and was buried here. Bowen's Island was a well-known garden spot and a popular setting for social gatherings and celebrations. Here the first Volksfest was held, and the Turnverein, and German Athletic Club, performed. During the 1870s it was the site of Wolfram's Central Garden, a pleasure resort. Mary Elizabeth Bowen died in 1903. During the 1920s the river was diverted, and Bowen's Island became part of the San Antonio mainland. (1985)

The Story

This peninsula in the San Antonio River, once bounded by water on three sides and the Concepcion Acequia on the fourth, was bought in 1845 by Philadelphia native John Bowen. He and his family built a seven-room home, planted orchards and vineyards, and ran a waterwheel-irrigated truck farm; Bowen served as city postmaster and treasurer and, a staunch Unionist, reportedly sheltered fugitive slaves. The island became a beloved gathering spot, hosting the first Volksfest and the German Turnverein before the river was diverted in the 1920s and joined it to the mainland.

Why it matters

Bowen's Island captures the cultural blend of 19th-century San Antonio, where an Anglo Unionist's farm became a stage for German American festival life on land shaped by Spanish colonial acequias.

The story behind this marker

AI context

The era

When John Bowen bought his little peninsula in 1845, San Antonio was in the middle of one of the great hinge moments in its history. Texas was leaving behind its brief life as an independent republic and joining the United States that very year, and the town on the river was still shaped far more by its Spanish and Mexican past than by the Anglo-American future rushing toward it.

You can read that layered past in the land itself. The tract was bounded on three sides by the San Antonio River and on the fourth by the Concepcion Acequia — one of the hand-dug irrigation channels the Spanish missions had carved across the valley more than a century earlier. Bowen bought the property from Maria Josefa Rodriguez de Yturri, a name that reminds you the deed passed from an established Tejano family to a newcomer from Philadelphia.

This was a frontier crossroads where cultures met rather than replaced one another. Spanish-colonial waterworks, Mexican landholders, an eastern Anglo settler, and — soon — a wave of German immigrants all left their mark on the same few acres. The story of Bowen's Island is really the story of nineteenth-century San Antonio in miniature.

People & events

John Bowen paid $300 for his island and set about making it a home. He and his wife, Mary Elizabeth, raised six children in a seven-room house here, and they treated the land with the care of people who meant to stay. They planted fruit trees and grapevines, and on the east bank of the river they built a waterwheel to lift water onto their truck farm — a working garden that fed both the family and the town.

Bowen was also a public man. Through the 1840s and 1850s he served San Antonio as United States postmaster and as city treasurer, jobs that put him at the center of civic life. He was, the marker tells us, a staunch Unionist, and family tradition holds that he sheltered people fleeing slavery. That is remembered as family tradition rather than documented fact, and it's worth honoring exactly as it comes down to us — a story a family kept about a man who held unpopular convictions in a place and time when they carried real risk.

Bowen died on the island in 1867 and was buried in the ground he had cultivated. Mary Elizabeth lived on until 1903, long enough to see the garden spot her family had made pass into a new chapter of the city's social life.

Its place in the American story

It is easy to picture the American frontier as a lonely cabin at the edge of the map. Bowen's Island tells a richer and truer story: of a diverse, cosmopolitan community taking shape at the meeting point of Spanish, Mexican, Anglo, and German cultures in the years around statehood.

The island's later life makes the point vividly. It became a beloved gathering place, and it hosted the first Volksfest — a German folk festival — while the Turnverein, a German athletic and civic society, performed here. In the 1870s the grounds became Wolfram's Central Garden, a pleasure resort. Across the nineteenth century, German immigrants poured into central Texas and reshaped its towns, its music, its food, and its public celebrations, and this small peninsula became one of the stages where that immigrant culture flourished in the open air.

There is a national thread in Bowen himself, too. That a Philadelphia-born Unionist held public office in a Southern town, and that his family remembered him as a protector of the enslaved, is a reminder that the great divisions of the Civil War era ran through individual households and river-bend farms, not just through armies and capitals.

If you visit

The first thing to understand when you visit is that the island is no longer an island. In the 1920s the river was diverted, and the peninsula was joined to the San Antonio mainland — so you'll be standing on ground whose very shape has changed since Bowen's day. Part of the pleasure of the place is imagining the water that once curled around three sides of it.

Let the marker slow you down. Read it, then look for the lay of the land: the course of the river, any hint of the old acequia line, the gentle rise where a seven-room house and its orchard once stood. This was a working farm and, later, a festival ground, so picture both — grapevines and a turning waterwheel on one hand, brass bands and folk dancing on the other.

Bowen's Island fits naturally into a day spent tracing San Antonio's river and its Spanish-colonial past. If you're following the acequias and missions that gave this valley its shape, this spot adds a human-scale chapter to the story — one family, one garden, and a community that gathered here to celebrate.

One of San Antonio's early stone residences, this house had its first floor and basement built by about 1857 for attorney Newton A. Mitchell and his wife Catherine.

A San Antonio business and civic leader, Oge had the noted architect Alfred Giles enlarge and remodel the home in Neo-Classical style.

Site of the Home of Dr. Ferdinand Ludwig Herff

San Antonio, TX

Ferdinand Ludwig von Herff came to Texas in 1847 as one of Die Vierziger, the idealistic "Forty" who tried to found a utopian commune called Bettina in the Hill Country. When that dream collapsed within a year, he returned to Germany, married, and came back for good, settling in San Antonio in 1850 and building this home in 1855. A German-trained surgeon of real distinction, he helped organize the county medical society, founded the city's first infirmary with the Sisters of Charity, and — though a Confederate surgeon — was quietly known for Union sympathies, practicing until he was nearly ninety.

Groos National Bank

San Antonio, TX

Frederick Groos, a German engineer, reached Texas in 1848 and won a government freighting contract during the building of Fort Duncan, sending long trains of ox carts across country plagued by raids. With his brothers he built the mercantile firm F. Groos and Co., where frontier banking meant money hidden in cotton bales and cart axles for safety on the road. In 1879 the family erected San Antonio's first purpose-built bank and took a national charter in 1912.
