Founded in 1325, Tenochtitlan was a city-state located on an island in Lake Texcoco. It served as the capital of the Aztec empire until the 1521, when the Spanish invaders claimed the city for Spain.
During its slightly less than 200-year existence, Tenochtitlan was one of the largest and most advanced cities in MesoAmerica. It was estimated to have a population of 200,000. Three giant causeways connected the island to the mainland. Canals criss-crossed the city, and chinampas, or floating gardens, were engineering to create fertile farm land.
In 1519, Spanish conquistador Hernan Cortes arrived in Tenochtitlan and launched an attack on the city that lasted nearly two years. The city fell on 13 August 1521, was leveled, and its ruins were built atop by the Spanish.
Today, a tiny portion of Tenochtitlan remains in what is modern-day Mexico City. Thousands of Aztec objects were unearthed in the late 1900s and the foundation of Templo Mayor was excavated. These finds offer visitors a small glimpse into the mighty Aztec Empire.
