The Museum of South Texas History is accredited by the American Alliance of Museums. It is located in downtown Edinburg at 200 North Closner Boulevard on the Hidalgo County Courthouse square. Founded in 1967 as the Hidalgo County Historical Museum in the 1910 Hidalgo County Jail, the museum has grown over the decades through a series of expansions to occupy a full city block. In 2003 following the completion of a 22,500 square foot expansion, the museum was renamed the Museum of South Texas History to better reflect its regional scope. Today, the museum preserves and presents the borderland heritage of South Texas and Northeastern Mexico through its permanent collection and the Margaret H. McAllen Memorial Archives and exhibits spanning prehistory through the 20th century.
