Procession in the monastery church to Kaisheim on the Danube Domenico Quaglio (1787-1837)

The picture has something of this: church, architecture, cathedral, building, goth like, abbey, arch, vault, city, window, monastery, indoors, turning point, Gothic, ancient.
Perhaps it’s a painting of a large group of people inside of a building with a stage in the middle of the room and a crowd of people on the other side.
