A post-Classic Maya archaeological site in Cancun's Hotel Zone, Quintana Roo, Mexico, discovered in 1923 by Raymond Merwin and Samuel Lothrop. Originally called Kin Ich Ahau Bonil ('king of the solar countenance'), the site spans the Late Preclassic through Late Post-Classic (300 BC-1500 AD). Its 47 structures served as a trade hub, royal burial ground, and astronomy centre along Caribbean maritime routes, with links to Chichen Itza and Edzna. Over 500 burials have been identified beneath residential platforms, and remains of post-Classic mural paintings survive on several structures.
