Guggenheim Museum Bilbao, art museum in Bilbao, Spain. It opened in 1997 as a cooperative venture between the Guggenheim Foundation and the Basque regional administration of northwestern Spain. The museum complex, designed by Frank O. Gehry, consists of interconnected buildings whose extraordinary free-form titanium-sheathed mass suggests a gigantic work of abstract sculpture. The interior space, organized around a large atrium, is mainly devoted to modern and contemporary art, particularly massive sculptures.
