Temple I (Temple of the Great Jaguar), is a monument to the ruler Ah Cacau. Rising 145 feet in the air, it was built around 700 AD. During his rule, (late 7th century AD), Ah Cacau created many of the spectacular temples that exist in Tikal today. His burial chamber was discovered at the base of Temple I, and much has been learned from his tomb. Buried along with him were ornamental jade, intricately carved bone, and sting-ray spines that were used for religious blood-letting.
