The Chapultepec aqueduct (in Spanish: acueducto de Chapultepec) was built to provide potable water to Tenochtitlan, now known as Mexico City. Tenochtitlan was the capital of the Triple Aztec Alliance empire (formed in 1428 and ruled by the Mexica, the empire joined together the three Nashua states of Tenochtitlan, Texacoco, and Tlacopan).[1] This fresh water was transported from the Chapultepec springs.[2] Two aqueducts following the same route from the springs were built by the Aztecs during the 15th century, the first destroyed by flooding and the second by the Spanish. After the Spanish conquest a colonial aqueduct was built, the ruins of which are located near Metro Sevilla.[3]
