Bosboom, Johannes – Interieur van de Domkerk te Trier, 1870-1880 Rijksmuseum: part 3

The picture has something of this: architecture, building, ancient, Gothic, church, stone, wall, city, antique, town, arch, vintage, cathedral, historic, urban.
Perhaps it’s a painting of a person standing in a room with a doorway and a person sitting on the floor in front of the doorway and another person standing.
