The Lost City of Tulum (PYRAMID BY SEA)

Tulum (Spanish pronunciation: [tuˈlun], Yucatec Maya: Tulu'um) is the site of a pre-Columbian Mayan walled city which served as a major port for Coba, in the Mexican state of Quintana Roo.[1] The ruins are situated on 12-meter-tall (39 ft) cliffs along the east coast of the Yucatán Peninsula on the Caribbean Sea.[1] Tulum was one of the last cities built and inhabited by the Maya and achieved its greatest prominence between the 13th and 15th centuries. Maya continued to occupy Tulum for about 70 years after the Spanish began occupying Mexico, but the city was abandoned by the end of the 16th century. Tulum is one of the best-preserved coastal Maya sites, and today a popular site for tourists.
