Musée d’Orsay, Paris
Building, Art Museum
This gigantic collection of impressionist and post-impressionist masterpieces (the biggest collection of such work in the world, in fact) can be found in what used to be a railway station. Originally the Gare d’Orsay, the building is one of the finest examples of the Beaux-Arts movements in France, with many of the period features like its gorgeous clocks maintained. It would take an impressive building to match a collection featuring some of the finest Manets, Van Goghs and Gauguins, but the Musée d’Orsay manages this feat.
