San Antonio is famous for its very popular River Walk, which began construction in 1939 and now consists of a 15-mile long network of sidewalks, buildings, and small tour boats that pass under arched footbridges as they meander down the San Antonio River, past restaurants, shops, entertainment venues, and hotels. San Antonio is also home to The Alamo, a historic Spanish mission and fortress established in the 18th century by Roman Catholic missionaries. In 1836 the Battle of the Alamo was a key event in the Texas Revolution, a war over land between Mexico and the Texian Army. It remains open to the public, along with several other historic sites in San Antonio.
