Uxmal is a large pre-Columbian city. The ruins are in Mexico today, in the state of Yucatán. According to the records of the Maya, the city was built around the year 500 AD. According to current research, about 25.000 people lived there. Most of the buildings that can be seen today were built between 700 and 1100. After 1200, there seems to be no new construction. The ruling family moved their capital elsewhere, and the population of the city declined.
