About Museum of South Texas History

Museum of South Texas History features prehistoric fossils, a steamboat replica, and exhibits on native peoples and European colonization across its galleries. Visitors explore the Rio Grande Legacy, a permanent bilingual exhibit sequence beginning with River Frontier, which traces the region's geological origins and frontier history with New Spain. The museum preserves the Old Jail, built in 1910 and originally housing the county sheriff's office, now part of the core collection. A 2003 expansion added a 22,500 square foot wing containing the Grand Lobby, Museum Store, and additional permanent exhibits. The venue hosts the Sunday Speaker Series and Museum Pláticas programs, along with cultural events. A visit suits anyone interested in South Texas and Northeastern Mexico borderland heritage spanning prehistory through the twentieth century. Museum of South Texas History stands in Edinburg, Texas, with free admission for children ages three and under, as detailed on mosthistory.org.
