The Maya Temple of the Great Jaguar in Tikal: Located in the Maya city of Tikal in present-day Guatemala, this temple was constructed in the eighth century C.E. and excavated by archeologists in the late nineteenth century. It served as the tomb of the Tikal ruler Jasaw Chan K’awiil I (682–734). Some 144 feet tall, it was topped by a three-room temple complex and a huge roofcomb showing the ruler on his throne. Carved on a wooden beam inside the temple is an image of the ruler protected by a huge jaguar along with illustrations of his military victories. (Peter M. Wilson/Alamy)
