Fodor's Expert Review Suermondt-Ludwig Museum

The smaller of the two Ludwig art institutions in town (the Ludwig Forum is the larger one) has a collection that concentrates paintings from the 12th to the early 20th century, including a sizable holding of 17th-century Dutch and Flemish works by the likes of Anthony Van Dyck and Frans Hals. It's also home to one of Germany's largest sculpture collections.
