The Alamo is a historic Spanish mission and fortress compound founded in the 18th century by Roman Catholic missionaries in what is now San Antonio, Texas, United States. It was the site of the Battle of the Alamo in 1836, a pivotal event of the Texas Revolution in which American folk heroes James Bowie and Davy Crockett were killed. Today it is a museum in the Alamo Plaza Historic District and a part of the San Antonio Missions World Heritage Site.
