This religious museum in the Convent of the Immaculate Conception, founded in 1599, offers a glimpse into the centuries-old customs of the cloistered nuns who live here. You can’t see the nuns (they’re cloistered, after all) but you can see their primitive bread-making equipment and dioramas of their stark cells, as well as some religious art. It's three blocks southeast of Parque Calderón.
