Named la Iglesia (the Church) by the Spanish, probably because it was located right next to the Nunnery, this temple is one of the oldest buildings at Chichén Itzá. It is of classic Puuc construction with an overlay of central Yucatan styles. The structure itself is rectangular with a single room inside and an entrance on the west side. One of the most photographed buildings at Chichen Itza, it’s exterior is almost completely covered with veneer decorations. Masks of Chac decorate two upper stories. Among the crowd of Chacs there are also an armadillo, a crab, a snail, and a tortoise. These represent the Maya gods, called bacah, whose job it was to hold up the sky.
