city, northwestern Federal District, central Mexico. Situated approximately 7,350 feet (2,240 m) above sea level in the Valley of Mexico, the city was founded in the 12th century and given the Aztec name meaning "anthill" because of its large population. It became famous for its slave market and the skill of its craftsmen in working precious metals. Hernan Cortes later set up smelters there to melt Mexican treasure into bullion. The Spaniards also destroyed the Aztec temple, and on its site there is a Dominican convent with a 17th-century church and an 18th-century rosary chapel.
