Although most of the stone structures at San Gervasio now lack their roofs and upper portions of their walls, archaeologists from Harvard and the University of Arizona compiled detailed plans of the remains in the early 1970s that allowed them to create reconstructed views of these buildings. Renderings of these reconstructions are illustrated in the guidebook offered for sale by the Cozumel Parks and Museum Foundation (FPMCQROO), an agency of the Mexican State of Quintana Roo and the agency responsible for the upkeep and maintenance of the State park that surrounds the National Monument of the ruins of San Gervasio, which is administered separately by the National Institute of Anthropology and History (INAH). More information about the archaeological park, including hours of operation, entrance fees, and directions are available on the FPMCQROO website CozumelParks.com
