Ukhtomsky, Konstantin Andreevich. Types of rooms in the Winter Palace. Commandant Entrance Hermitage ~ part 12

The picture has something of this: church, architecture, arch, monastery, column, castle, indoors, tower, city, cathedral, arcade, hallway, chapel, abbey, building, step, library, window.
Perhaps it’s a painting of a hallway with a man in a red coat and a woman.
