San Gervasio is the largest Mayan Ruins site on Cozumel, and also the most significant. It was a holy site, dedicated to Ixchel, the goddess of fertility. Mayan women would pilgrimage here from all over the country to pray at the temples of San Gervasio. The settlement dates back as far as 100 B.C., and was continually settled starting in 200 A.D. Today, several temples still stand, and while small compared to the massive ruins sites in the Riviera Maya, it is well worth a visit if you don't have the time or desire to make the trip over to Playa del Carmen on the ferry.
In the north of Cozumel is the temple complex of San Gervasio. The moon and fertility goddess Ix Chel was worshipped in this temple complex. Pilgrims desiring children are known to have come here from all over Yucatan and the neighboring provinces.
