It’s tempting to feel sorry for this fine arts museum, since the Guggenheim gets all the attention. But it’s worth visiting for two reasons: First, its tidy linear organization by art historical category seems a reassuring return to order after the disorienting galleries of the Guggenheim. Second, it has a few outstanding pieces of art you’d be sorry to miss. Some big names of Spanish painting are represented by mostly minor works, including Velázquez, Zurbarán, El Greco, and Goya. But be sure to catch the Spanish Gothic painting and sculpture, with its images of suffering Christs, sad-eyed Madonnas, and otherworldly angels. Regional paintings from the early 20th century show both folkloric subjects and a striking sense of moral outrage, particularly about the mistreatment of miners and factory workers.
