Bryan Mound
Freeport, Brazoria County, Texas
Marker Inscription
During the first decade of the 20th century, mining engineers discovered sufficient quantities of sulphur deposits at Bryan Mound to lead to the organization of the Texas Freeport Sulphur Co. in 1912. The commercial production of sulphur at Bryan Mound was largely responsible for the development of the Freeport townsite. Employment of a liquid extraction procedure to mine the sulphur, known as the Frasch process, signified one of the earliest uses of this method in Texas. The Bryan Mound operation closed in 1935, after having produced 5 million tons of sulphur. (1968, 1986)

The Story
Early in the 20th century, mining engineers found rich sulphur deposits at Bryan Mound, spurring the founding of the Texas Freeport Sulphur Co. in 1912. Their success drove the growth of the Freeport townsite itself. The operation was among Texas's earliest to use the Frasch process—superheated water pumped underground to melt and lift the sulphur—producing five million tons before it closed in 1935.
Why it matters
Bryan Mound anchored the Gulf Coast's sulphur industry and helped pioneer an extraction method that transformed American chemical manufacturing.

Stringfellow Orchards
Hitchcock, TX
In 1883, horticulturist Henry Martyn Stringfellow established an experimental garden and orchard here on the Texas coastal plain. His 1890 treatise on innovative organic growing methods drew a wide following among fruit and vegetable growers in Japan, Germany, and the United States. Silver medals at two world's fairs and further publications cemented his standing as one of his era's leading experimental horticulturists.
Schuster Home
Freeport, TX
Built in 1917 on part of the Freeport town site, the Schuster home was raised largely by George Schuster's carpenter sons on heavy cedar blocks, with a wraparound porch, tapered columns, and milled cypress walls that made it one of Freeport's first and finest wooden houses. Family members lived in it for generations, keeping much of the original furniture in place. In 2003 the Schuster descendants formed a corporation and entrusted the house to a historical society, which restored it over a decade and opened it to the public as a museum.
Freeport National Bank (Freeport Sulphur Company Building)
Freeport, TX
The Freeport Sulphur Company literally built the town around it: incorporated in 1912, it laid out Freeport on the west bank of the Brazos as a duty-free port to move sulphur from the Bryan Mound mines to world markets. The Freeport National Bank raised this one-story building with a built-in vault in 1913, and by 1918 the sulphur company had bought adjoining land and added a second story. The Classical Revival structure, with its brick corbelling and flat-arched windows, reflects the confident commercial architecture of an early-20th-century boomtown.
Stringfellow Ranch
Freeport, TX
Robert Edward Lee Stringfellow started on a Brazoria County cattle ranch at fourteen and soon had a herd of his own, opening a Velasco meat market in 1890 that fed the crews building jetties at the mouth of the Brazos. His holdings grew to 20,000 acres and he became an early investor in the new town of Freeport. After a 1932 hurricane injured him, his wife Nannie ran the ranch and the family's Freeport interests for decades more.
