Ancient ruined Mayan city in Mexico's Yucatán state.
Chichén Itzá was founded by the Maya about the 6th century AD in an arid region where water was obtained from natural wells called cenotes. The city was invaded in the 10th century
probably by a Mayan-speaking group under strong Toltec influence
and the invaders constructed another series of buildings, including the famous stepped pyramid known as El Castillo and a ball court. The site, though largely abandoned by the time the Spanish arrived in the 16th century, remained sacred to the Maya people. It was designated a World Heritage site in 1988.
