Unlike some of the other museums on this list, the structure that houses this museum is as beautiful as the artwork within. The extensive collection features works from the 13th to the 20th centuries, including those by Monet, Manet, Rubens, Van Gogh, Picasso, Seurat, and other European artists. Earlier works date from approximately 2500 B.C. An original cast of Rodin's "The Thinker" dominates the museum entrance. After you wander the beautiful insides of Legion of Honor, take time to check out its distinct neighborhood, which includes cozy Clement Street and Lands End Recreational Area, which features nature trails with stunning views of the Pacific.
