Brownsville, Cameron County
Constructed in 1905 to serve as a food storage facility, this building was abandoned one year later when Fort Brown was closed. Upon reactivation of the post during Mexican border disturbances, the building served as a guardhouse and jail. Among those quartered here were political refugees following the Battle of Matamoros on June 4, 1913. The structure features a loading dock and a shed roof with gabled dormer over the entrance.
