Tulum (meaning Trench) is the site of a pre-Columbian Mayan walled city, not very far from Playa del Carmen. Tulum was one of the last cities built and inhabited by the Maya; it was at its height between the 13th and 15th centuries. It is one of the rare cities built by Mayans because it was a walled city, perched on a 12m cliff facing the Caribbean sea.
There are three major structures of interest at the Tulum archaeological site. El Castillo, the Temple of the Frescoes, and the Temple of the Descending God.
Even though, the site is more in a ruinous state compared to other sites, it still draws thousands of visitors every year.
