Site of first federal fort established in Texas, 1848, (three years after Texas joined the U.S.), to guard the frontier. But German settlers had already arrived and established a treaty of friendship with Comanches residing in the area. Perhaps unique among Indian treaties, it was never broken by either side. With mutual trust, fort became a center of commerce between settlers, Indians, and soldiers.

The fort, with 21 buildings, served until 1853. The only original structure still standing was the post guardhouse, now restored. Visitor center exhibits model of the fort and plans for extensive restorations.

Also on display are artifacts, documents, and fascinating details about trade in bear grease, sugar, rice, and coffee. Beef was four cents a pound. Operated by the Gillespie County Historical Society; two miles east on U.S. 290. No Admission fee.
