History and description
This Maya site may formerly have been known by the name Zama, meaning City of Dawn, because it faces the sunrise. Tulum stands on a bluff facing east toward the Caribbean Sea. Tulúm is also the Yucatan Mayan word for fence, wall or trench. The walls surrounding the site allowed the Tulum fort to be defended against invasions. Tulum had access to both land and sea trade routes, making it an important trade hub, especially for obsidian. From numerous depictions in murals and other works around the site, Tulum appears to have been an important site for the worship of the Diving or Descending god.
Tulum was first mentioned by Juan Díaz, a member of Juan de Grijalva's Spanish expedition of 1518, the first Europeans to spot Tulum. The first detailed description of the ruins was published by John Lloyd Stephens and Frederick Catherwood in 1843 in the book Incidents of Travel in Yucatan. As they arrived from the sea, Stephens and Catherwood first saw a tall building that impressed them greatly, most likely the great Castillo of the site. They made accurate maps of the site’s walls, and Catherwood made sketches of the Castillo and several other buildings. Stephens and Catherwood also reported an early classic stele at the site, with an inscribed date of AD 564 (now in the British Museum's collection). This has been interpreted as meaning that the stele was likely built elsewhere and brought to Tulum to be reused.
Work conducted at Tulum continued with that of Sylvanus Morley and George P. Howe, beginning in 1913. They worked to restore and open the public beaches. The work was continued by the Carnegie Institution from 1916 to 1922, Samuel Lothrop in 1924 who also mapped the site, Miguel Ángel Fernández in the late 1930s and early 1940s,
William Sanders in 1956, and then later in the 1970s by Arthur G. Miller. Through these later investigations done by Sanders and Miller, it has been determined that Tulum was occupied during the late Postclassic period around AD 1200. The site continued to be occupied until contact with the Spanish was made in the early 16th century. By the end of the 16th century, the site was abandoned completely.
