The monastery of San Juan Bautista in Tetela del Volcán is one of the Monasteries on the slopes of Popocatépetl and a UNESCO world heritage site. It was built by the Dominicans in the first half of the 16th century and was even visited by Hernán Cortés. The exterior has arcades that surround the complex but are partially hidden by trees. The upper parts of the walls around the complex are covered in paint, the lower floor of the cloister has figures depicted in the arches and walls. In the vaults over the walkways, there are numerous cherubs defeating evil spirits and some even fighting with each other. One unique architectural element is the Moorish-style wood been roofing in the sacristy.
