Tutukin, Peter V.. Types of rooms in the Winter Palace. Pavilion Hall Hermitage ~ part 12

The picture has something of this: architecture, ceiling, indoors, column, arch, castle, vault, arcade, tower, building, marble, chandelier, museum, bedrock, historic, city, church.
Perhaps it’s a painting of a man and a woman standing in a large room with columns and arches on either side of the room and a staircase leading up to the second floor.
