Fodor's Expert Review Museum Ludwig

This museum is dedicated to art from the beginning of the 20th century to the present day. Its American pop-art collection (including Andy Warhol, Jasper Johns, Robert Rauschenberg, Claes Oldenburg, and Roy Lichtenstein) rivals that of many American museums. It is also home to the third-largest Picasso collection in the world, something one might not expect to find in Cologne.
