Frescoes on the right wall, 1365-68, Cappe Andrea di Bonaiuto da Firenze (fl.1343-1377)

The picture has something of this: church, saint, architecture, god, Mary, mosaic, cathedral, spirituality, people, fresco, arch, Renaissance, religious, building, aura, altar.
Perhaps it’s a painting on the side of a building with a lot of people standing.
