Located on a hill in the Tepozteco Valley, the monastery of La Natividad de Nuestra Señora in Tepotzlán was built between 1550 and 1564 and still towers over the other buildings in the town. It initially began with only five Dominican friars. The large atrium has a large stone cross with symbols of the Passion. There is an open chapel and chapels in the capillas posas in the corners, but most of these are in ruins. The cloister contains friezes with the coat of arms of the order. There is evidence of syncretism of indigenous and Catholic beliefs such as the image of an angel with European facial features but with eagle's wings, similar to those which can be found on Quetzalcoatl. In the interior, there is a fresco with a xoloitzcuintle dog with a torch in its mouth and a border around the walls with squash flowers and roses, surrounded with precious stones, including a native one called “chalchihuite.” The plaza in front of the atrium of the monastery in Tepoztlán is crowded with a tianguis market which sells everything from basic food staples to New Age paraphernalia.
