Museo del Carmen
Erected by Carmelite friars with the help of an Indigenous chieftain between 1615 and 1628, this church—with its domes, frescoes, vaulted archways, fountains, and gardens—was never actually a convent, despite its name. Though some locals might tell you otherwise, nuns never actually lived here. The church still operates (you can enter it for free from a separate entrance next door), but part of the church complex has been converted into Museo del Carmen, with a fine collection of 16th- to 18th-century religious paintings and icons. Much of the religious art (along with a captivating collection of photos that depict San Ángel and the southern portions of the city during the early 20th century) is on the second floor of the adjoining Casa de Acueducto, which overlooks another courtyard fringed by an interesting ancient aqueduct. It's also worth visiting the dozen-or-so mummified corpses tucked away in the crypt—a creepy but fascinating sight, for sure. For a perhaps much-needed breath of fresh air, saunter out to the gracious rear garden, with its shady trees and benches. There's usually an excellent temporary exhibit as well, typically touching on some element of Mexico City history and culture.
