San Antonio was named for the Portuguese St. Anthony, whose feast day is on June 13, when a Spanish expedition stopped in the area in 1691. The city has a strong military presence—it is home to Fort Sam Houston, Lackland Air Force Base, Randolph Air Force Base, and Brooks City-Base, with Camp Bullis and Camp Stanley right outside the city. Furthermore, Kelly Air Force Base (now Port San Antonio) operated out of San Antonio until 2001, when the airfield was transferred over to Lackland AFB and the remaining portions of the base became an industrial/business park. The decision to close Kelly and consolidate its resources came from the 1995 BRAC. San Antonio is also home to the South Texas Medical Center, the only medical research and care provider in the South Texas region.
Famous for the River Walk, the Alamo, and home to the SeaWorld San Antonio and Six Flags Fiesta Texas theme parks, the city is visited by approximately 26 million tourists per year according to the San Antonio Convention and Visitors Bureau. San Antonio is also home to the first museum of modern art in Texas, known as the McNay Art Museum.
