It is also described as the scene of the first serious agitation and armed conflict of the Texas Revolution, and has been called the \"Birthplace of the Texas Revolution.\"","narrative":"Fort Anahuac is an archeological site about one mile south of Anahuac, Texas, on the edge of a terrace above the Trinity River delta and Trinity Bay. Mexico built it in 1830 as a small fort and customs house, using about 160 soldiers under Col. Juan Davis Bradburn. Its brick walls were more than seven feet thick, and it was armed with two 18-pound pivot guns. Settlers resented the fort's customs enforcement, its restrictions on immigration, and the labor and materials Bradburn demanded. Conflict followed, and prominent Texans including Patrick C. Jack and William B. Travis were held there. The fort is credited with several firsts of the Texas Revolution, including the Turtle Bayou Resolutions and early armed clashes. Today only foundations survive, mostly below ground. Local residents mined the bricks for about 150 years, and a 1960s excavation disturbed part of the site. A 1977 magnetometer survey found anomalies that may mark other features. The site lies within a county park.","period_of_significance":"1830-1836 (?)","architect_builder":"Republic of Mexico","architectural_style":null,"criteria":[],"status_note":"Now a county park with historical markers; only brick wall foundations remain, mostly underground, and the site is described as heavily disturbed by brick mining and earlier excavations.
