2 Best Sights in Valladolid, Yucatán and Campeche States

Five long blocks away from the main plaza is the 16th-century, terra-cotta Ex-Convento e Iglesia San Bernardino, a Franciscan church and former monastery. The church was actually built over Cenote Sis-Há, which provided the monks with a clean water source. You can view the cenote through a grate in the well house, where much of the original stone still remains. If a priest is around, ask him to show you the 16th-century frescoes, protected behind curtains near the altarpiece. The lack of proportion in the human figures shows the initial clumsiness of indigenous artisans in reproducing the Christian saints.

On the south side of the town's main plaza stands the large Iglesia de San Servacio, sometimes spelled "San Gervasio." Although many refer to it as a catedral, it is not the seat of the diocese—that's in Mérida. Its limestone exterior is impressive, but the interior is rather plain. The church makes a stunning anchor for the plaza when illuminated at night.
