Old Stone Fort Museum, Historical museum in Nacogdoches, Texas.

The Old Stone Fort Museum is a 1936 replica of Antonio Gil Y'Barbo's circa 1779 iron-ore mercantile house, built at a different location on the Stephen F. Austin State University campus in Nacogdoches. The original was never a fort despite its nickname. The replica was funded by the New Deal and the Cum Concilio civic organization, and dedicated on October 16, 1936.

Antonio Gil Y'Barbo built the original Stone House around 1779 of native iron ore as a mercantile house; it was never a fort despite the name. Sold in 1805 and 1806, it housed the House of Barr and Davenport trading firm and later served as a courtroom under Judge Robert McAlpin Williamson in 1837. The Perkins family dismantled it in 1902; Cum Concilio preserved some stones, and a replica funded by the New Deal was dedicated on October 16, 1936.

The building's nickname comes from its iron-brick construction, though it never served as a fort. Merchants Peter Samuel Davenport, Luther Smith and Edward Murphy ran the House of Barr and Davenport there, an import-export business trading with the indigenous tribes of the area. The 1936 replica was funded by the New Deal and built with help from the Cum Concilio civic organization.

The museum is located directly on the university campus and is easily accessible on foot or by car. Plan at least an hour to browse the exhibits and explore the grounds comfortably.

The replica was built with funding from Franklin D. Roosevelt's New Deal program and dedicated on October 16, 1936, on the campus of what was then Stephen F. Austin State College. Some original stones from the 1779 building were saved by the Cum Concilio civic club, which in 1907 used them for a small structure in Washington Square.
