Designed by Austin architect Charles H. Page, this brick schoolhouse was completed in 1926 and named for County Judge G.A. Welhausen (1862-1944). Twenty-year-old Lyndon B. Johnson came to Cotulla in 1928-29 and served as teacher and principal at the school, which served the city's Hispanic students for many years. Built in a classically inspired plan with a central block flanked by two low wings, the building features decorative tile panels.
