San Gervasio is an archaeological site of the pre-Columbian Maya civilization, located in the northern third of the island of Cozumel off the northeastern coast of the Yucatán Peninsula, in what is now the Mexican state of Quintana Roo. San Gervasio's pre-Hispanic name was Tantun Cuzamil, Mayan for Flat Rock in the place of the Swallows. The ruins were once a hub of worship of the goddess Ix Chel, an aged deity of childbirth, fertility, medicine, and weaving. Pre-Columbian Maya women would try to travel to San Gervasio and make offerings at least once in their lives.
The park is also a wildlife refuge and the local iguana population has become quite habituated to humans.
