Mayapan was the political and cultural capital of the pre-Columbian Maya civilization that occupied the Yucatán Peninsula between 1110 and 1450.
Located some 25 miles south-east of the Yucatán’s modern capital of Mérida, the ancient city is estimated to have once supported a population of 15,000—17,000 people.
The site has been excavated in various phases, beginning in 1939.
In total, the remains of 4,000 structures have been unearthed from within the city walls — most of them residences — alongside a ceremonial centre containing temples, colonnaded halls, and platforms for oration, dancing and the display of stone monuments.
