Chiesa della Madonna dell'Arco Oscuro

A two-room chapel cut into the tufa on viale delle Belle Arti, near Villa Giulia. The first room is modern, with ex-votos and a mosaic Annunciation; the second is the late eighteenth-century chapel proper, holding the arco oscuro itself with the Marian image walled in, and a Via Crucis of fourteen stations. A plaque outside reads Sacellum Matri Divinae Providentiae de Arcu Obscuro dicatum, and the arms of Innocent XI are on the entrance architrave.
