The Sacred Cenote is a sinkhole that is connected to Chichen Itza by a raised pathway. This large natural well may have given Chichén Itzá (“Well of the Itzáes”) its name. There is a second karst cave in the center of Chichén Itzá that was used as a source of water for Chichén Itzá’s residents. The use of the Sacred Cenote was exclusively ceremonial. Over the years, the murky water has yielded many artifacts including gold, jade, copper, turquoise, obsidian, copal or incense, pottery, rubber, shells and the bones of around 200 people who were thrown in as a sacrifice. According to Bishop Landa, men, women and children were thrown alive into it as a sacrifice to the gods in times of droughts.
