The ALAMO is a historic site in San Antonio, Texas, that was the site of a pivotal battle in the Texas Revolution. The mission was originally built by Spanish missionaries in the 18th century and served as a fort during the Texas Revolution. The Battle of the ALAMO was fought in 1836 between the Mexican army and a group of Texan revolutionaries, and resulted in a decisive victory for the Mexican army. The ALAMO has since become a symbol of Texan independence and is now a popular tourist destination.
