The monastery of San Juan Bautista in Tetela del Volcán was built by the Dominicans in the first half of the 16th century and was even visited by Hernán Cortés. It is at a high altitude near the volcano surrounded by pine forest in a relatively cold climate. 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. Many are of Augustinian monks. In the vaults over the walkways, there are numerous cherubs which are defeating evil spirits and some are even fighting with each other. One unique architectural element is the Moorish-style wood-beam roofing in the sacristy. There is a crafts market held here each Wednesday. The atrium have a series of frescos of very high quality, painted by a local indigenous artist in the 16th century. They were restored in 2008.
