…preserving and presenting the borderland heritage of South Texas an Northeastern Mexico

With its soaring main tower, the Museum of South Texas History (MOSTHistory) is a signature landmark on the north side of Edinburg’s Courthouse square. Accredited by the American Alliance of Museums, MOSTHistory occupies an entire city block with Spanish Revival buildings and landscaped parking areas. Founded in 1967 as the Hidalgo County Historical Museum in the 1910 Hidalgo County Jail, 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. Its collections include significant holdings relating to the American Civil War, including sabers, carbines and other weapons as well as bullets from the Palmito Ranch battle site and other reminders of the Civil War’s last land battle, fought near Brownsville in May, 1865.
