The only complete example of an aristocratic 18th-century Spanish colonial residence remaining in the United States. Built around 1749 as the headquarters of the captain of the Presidio de Béxar, it has ten rooms arranged around a courtyard, with thick adobe walls, carved wooden lintels, and a peaceful garden. The interior is furnished in period style — heavy colonial furniture, iron locks, tiled floors.
The building was falling apart by the early 20th century, used as a tamal shop, a saloon, and a school at various points. It was purchased by the city in 1928 and carefully restored. A small admission fee; open Tuesday–Sunday. One of the most authentic colonial interiors in the American Southwest.
