The Cloisters, San Lorenzo fuori le mura Christoffer Wilhelm Eckersberg (1783-1853)

The picture has something of this: architecture, arch, monastery, hallway, arcade, indoors, church, abbey, castle, building, Gothic, home, vault, house, tower, stone.
Perhaps it’s a painting of a hallway with arches and a couple of people standing on the other side of the hallway and looking at a painting on the wall.
