This enormous complex stands on nearly two city blocks and includes cloisters, a convent, and a shaded arcade that runs along the length of the public square. Look for indigenous symbols woven into the church’s design and a Moorish influence in the gold-leaf interior. Among the staggering 3,500 works of art inside are paintings from the famed Quito School.
Walking tours include the church, the Presidential Palace, La Compañía Church, and other old town landmarks. If you want to explore a bit farther, tack on a trek to Quilotoa Crater Lagoon to hike around the dormant volcano, and stop at Andean market towns such as Saquisili, Pujili, and Tigua.
