Architecture
Tulum has architecture typical of Maya sites on the east coast of the Yucatan Peninsula. This architecture is recognized by a step running around the base of the building which sits on a low substructure. Doorways of this type are usually narrow with columns used as support if the building is big enough. As the walls flare out there are usually two sets of molding near the top. The room usually contains one or two small windows with an altar at the back wall, roofed by either a beam-and-rubble ceiling or being vaulted. This type of architecture resembles what can be found in the nearby Chichen Itza, just on a much smaller scale.
Tulum's wall
Windows in the Castillo's sea-facing wall.
Tulum was protected on one side by steep sea cliffs and on the landward side by a wall that averaged about 3–5 meters (9.8–16.4 ft) in height. The wall also was about 8 m (26 ft) thick and 400 m (1,300 ft) long on the side parallel to the sea. The part of the wall that ran the width of the site was slightly shorter and only about 170 meters (560 ft) on both sides. Constructing this massive wall would have taken an enormous amount of energy and time, which shows how important defense was to the Maya when they chose this site. On the southwest and northwest corners there are small structures that have been identified as watch towers, showing again how well defended the city was. There are five narrow gateways in the wall with two each on the north and south sides and one on the west. Near the northern side of the wall a small cenote provided the city with fresh water. It is this impressive wall that makes Tulum one of the most well-known fortified sites of the Maya.
Most famous buildings
There are three major structures of interest at the Tulum archeological site. El Castillo, the Temple of the Frescoes, and the Temple of the Descending God.
Temple of the Frescoes
Among the more spectacular buildings here is the Temple of the Frescoes that included a lower gallery and a smaller second story gallery. The Temple of the Frescoes was used as an observatory for tracking the movements of the sun. Niched figurines of the Maya “diving god” or Venus deity decorate the facade of the temple. This “diving god” is also depicted in the Temple of the Diving God in the central precinct of the site. Above the entrance in the western wall a stucco figure of the “diving god” is still preserved, giving the temple its name. A mural can still be seen on the eastern wall that resembles that of a style that originated in highland Mexico, called the Mixteca-Puebla style, though visitors are no longer permitted to enter.
Temple of the Descending God
The Temple of the Descending God consists of a single room with a door to the west and a narrow staircase that was built on top of another temple that served as its base.
In the niche located at the top of the door stands a sculpture that’s found throughout Tulum. He has wings, a headdress, and holds an object in his hands.
El Castillo
Also in the central precinct is the pyramid, which is 7.5 m (25 ft) tall. The Castillo was built on a previous building that was colonnaded and had a beam and mortar roof. The lintels in the upper rooms have serpent motifs carved into them. The construction of the Castillo appears to have taken place in stages. A small shrine appears to have been used as a beacon for incoming canoes. This shrine marks a break in the barrier reef that is opposite the site. Here there is a cove and landing beach in a break in the sea cliffs that would have been perfect for trading canoes coming in. This characteristic of the site may be one of the reasons the Maya founded the city of Tulum exactly here, as Tulum later became a prominent trading port during the late Postclassic.
