The capital of the Aztec Empire was Tenochtitlán, located on an island in Lake Texcoco in present-day Mexico City. Founded in 1325, Tenochtitlán was a remarkable city known for its advanced architecture, intricate canal system, and vibrant markets. It served as a political, religious, and cultural center of the Aztec civilization. The city was home to grand temples, such as the Templo Mayor, and was a hub of trade and tribute collection. Tenochtitlán's impressive urban layout and significance made it one of the most influential cities in pre-Columbian America until its capture by Spanish conquistadors in 1521.
