San Antonio, formally the City of San Antonio, is the seventh largest city in the United States of America and the second largest in the state of Texas, with a population of 1,409,019 people. From 2000 to 2010, it was the fastest growing among the top ten biggest cities in the United States, and second from 1990 to 2000. The city is located on the southern tip of an urban megaregion known as the Texas Triangle, which spans South and Central Texas.
San Antonio is the county seat of Bexar. Recent annexations have expanded the city’s limits into Medina County and into Comal County, however only for a very small area near the community of Garden Ridge. The city is similar to other western metropolitan centers in that it has sparsely inhabited regions and a low population density beyond the city boundaries. The San Antonio–New Braunfels Metropolitan Statistical Area is centered on San Antonio. The metropolitan area, often referred to as Greater San Antonio, has a population of about 2.4 million, according to 2015 US Census estimates, making it the 25th-largest in the United States and the third-largest in the state of Texas. The metropolitan region is anticipated to continue expanding due to growth along the Interstate 35 and Interstate 10 corridors to the north, west, and east.
San Antonio was named in 1691 by a Spanish expedition in the region after Saint Anthony of Padua, whose feast day is June 13. Spanish colonial missions, the Alamo, the River Walk, the Tower of the Americas, the Alamo Bowl, and Marriage Island are all important features. Commercial entertainment includes SeaWorld and Six Flags Fiesta Texas amusement parks, and the city receives around 32 million visitors each year, according to the San Antonio Convention & Visitors Bureau. The city is home to the San Antonio Spurs, a five-time NBA champion, and hosts the annual San Antonio Stock Show & Rodeo, one of the biggest such events in the nation.
Fort Sam Houston, Lackland Air Force Base, Randolph Air Force Base (all of which comprise Joint Base San Antonio), and Lackland AFB/Kelly Field Annex are situated in San Antonio, while Camp Bullis and Camp Stanley are located outside the city. Kelly Air Force Base was based in San Antonio until 2001, when it was moved to Lackland Air Force Base. Port San Antonio, an industrial/business park, was established on the remainder of the base. San Antonio is home to six Fortune 500 firms and the South Texas Medical Center, the region’s only source of medical research and services.
On July 5, 2015, UNESCO designated the San Antonio Missions National Historical Park, together with the Alamo, as a World Heritage Site. The San Antonio Missions become the United States’ 23rd World Heritage Site, joining the Grand Canyon and the Statue of Liberty on the list.
