The Ex-monastery of Santiago Apóstol is located in the town of Cuilapan de Guerrero in the Mexican state of Oaxaca. The fortress-like complex is easily seen from the highway as one travels south from the capital city of Oaxaca on the road leading to Villa de Zaachila, and it is visited by both Mexican and international tourists. The complex is located on a small hill which gives it a view of much of the valley area. It is one of the most extravagant and elaborate colonial era constructions in Oaxaca, but it is often overlooked in favor of churches and monasteries located in the Mexico City area. Built of green quarried stone and river rocks, it is a quiet place where footsteps can echo in the hallways. The extravagances of the site, including the tall basilica, the elaborate baptismal font, the Gothic cloister and murals remain as national treasures. The decorative work of the monastery, especially its murals, are important because they show a systematic blending of indigenous elements into the Christian framework, done in order to support the evangelization process in the local Mixtec and Zapotec peoples.
