On the corner of one of Cusco’s most extraordinary streets, Hatunrumiyoc, a pedestrian alleyway lined with magnificent Inca stonemasonry, the Museum of Religious Art is housed in a handsome colonial palace that previously belonged to the Archbishop of Cusco (before that, it was the site of the palace of Inca Roca and then the home of a Spanish marquis). Inside is a nice collection of colonial religious paintings, notable for the historical detail they convey, but the extravagant old house — with its impressive portal and Moorish-style doors, balcony, carved-cedar ceilings, stunning stained-glass windows, and small chapel — is pretty nearly the main draw.
