interior of a modern building with a long, narrow hallway

interior of a modern building with a long, narrow hallway. The walls are white, with a large black triangle painted on one side, and a pink triangle on the opposite side. The hallway is illuminated by natural light filtering through skylights in the ceiling. There are a few people walking in the hallway, and some standing on the side. The flooring is tiled, and the hallway extends to the distance. This appears to be the interior of the Museu Nacional d'Art de Catalunya in Barcelona, Spain (41.383, 2.167).
