Sometimes The Space is as Spectacular as the Collection

When you take factory delivery on a new Mercedes, you get two free tickets to the Mercedes Museum in Stuttgart.  The Museum has a spectacular collection, the collection would be impressive in a Sear's store.  The Museum is in a spectacular building, the tour route is circular, moving from floor to floor, around the central atrium.  The building without the collection, would be worth the visit.  

Have you ever been in a museum where the building was better than the collection?
