Ex-Convento de San Francisco y Catedral de Nuestra Señora de la Asunción

The Ex-Convento de San Francisco is the oldest surviving Franciscan monastery complex in continental America, begun in the 1520s, and today its church functions as the Catedral de Nuestra Señora de la Asunción, seat of the Diocese of Tlaxcala. Visitors enter through a plain stone facade into a single nave notable for its Mudejar-style coffered wooden ceiling, an artesonado of interlocking geometric panels carved in the Moorish tradition brought by early Spanish friars, one of the few such ceilings surviving in Mexico. The adjoining atrium holds one of the earliest open-air chapels built for evangelizing indigenous Tlaxcalans, and the bell tower, built apart from the main structure, offers views over the Plaza de la Constitución below. A visit to the cathedral and grounds alone takes 30-45 minutes, while continuing into the attached Museo Regional galleries, which occupy the former convent cells and cloister, extends the visit to 90 minutes or more. The cloister's stone arcades and a small garden courtyard connect the cathedral to the museum wing. Weekday mornings are quietest, since the cathedral hosts regular services and is comparatively busier on Sundays and during the annual October Feria de Tlaxcala. The coffered ceiling photographs best in the soft indirect light of mid-morning, when the nave's high windows illuminate the wood tones without harsh contrast.
