Temple of the Frescos, or Templo de las Pinturas in Spanish. It is one of the best preserved structures here. It's also of major interest in the ancient city for its iconography. It is dated Late Post-Classic, which is the period between 1400-1550. Mythological themes on its murals represented death, the underworld and re-birth. Venus and the sun play key roles in defining characteristics of both art and architecture of the city. The sacred and the profane were intertwined at Tulum, due to its importance as a predominant trade center, and a major ceremonial city. Like other structures, it's made of a number of structural add-ons that evolved over time. It initially began as a simple building. Later additions include the column gallery you see surrounding the initial structure, the second floor, the buttress in the back to support the second floor and the low rear stepped platform. They answered religious and ceremonial needs that evolved through time. The frescos on the facade belong to the Descending God in the center and other figures with feathers on each side.
