Upon entering the church, one can see underneath the choir, fragments of murals showing Eagle and Jaguar warriors dialoguing, indicated by Aztec speech scrolls. Inside the nave is a large sequence of battle murals in enormous friezes that extend from under the choir long both sides. On the south wall, Eagle, Jaguar and Coyote warriors are dressed in animal skins, robes and feathered helmets, all fighting one another with obsidian swords and other weapons. The scenes depict decapitations and the dragging of prisoners against a landscape rich in foliage. Along the north wall, these warriors battle supernatural creatures such as a centaur which wears a headdress of quetzal feathers and figures of pregnant women emerging from acanthus buds.
