St. Bernard of Sisal (San Bernadino de Sisal), Valladolid, Yucatán, 16th Century
The Franciscans founded the monastery in 1552, and the church was consecrated in 1560. Building was complete by 1588. San Bernadino de Sisal has the distinction of being one of the few monasteries built on top of a cenote (sinkhole). Given the weight of the building, the underground river delayed and complicated construction of the complex. In the 17th century a well house or noria was built over the opening to the cenote to provide water.
