Tulum

An ancient building at Tulum, on the coast of Quintana Roo, Mexico.



Tulum was the largest Maya coastal city and the only Maya city known to have been inhabited when the Spanish arrived. Its buildings exhibit classic Maya architecture. The Temple of the Frescoes, for instance, which retains faint traces of blue-green frescoes, has a vaulted roof and triangular architecture. Other structures of note include the Castillo, the largest and most renowned building, which stands at the edge of a 40-foot cliff; and the Temple of the Descending God, named for a carving over the doorway of a winged god plunging toward Earth.
