Although little remains of the old presidio (fort) other than buried foundation walls, this small park does a good job of presenting the region's Spanish colonial history. Park exhibits focus on the Spanish soldiers, Native Americans, religion, and contemporary Hispanic culture in southern Arizona. Also on the grounds is the old Tubac School, built in 1885 and the oldest schoolhouse in the state. Living-history presentations are staged October through March on the first and third Fridays of the month between noon and 3:30pm. Among the characters you'll meet are Spanish soldiers, settlers, and friars.
