La Iglesia (The Church) - Chichen Itza

The Iglesia is rectangular with a single room inside and an entrance on the west side. The outside wall is completely covered with veneer decorations, which extend clear up to the roof comb. The frieze is bounded at ground level by a stepped fret motif and above by a serpent; the stepped fret motif is repeated on the bottom of the roof comb. The most important motif of the decoration is the Chac god mask with a hooked nose standing out on the corners of the building.
