The oldest museum in Cologne, it houses a highly-regarded collection of 13th to 19th century European painting and now occupies a striking postmodern cube designed by O.M. Ungers. It's an important stop for anyone interested in seeing work from the Cologne School, Dutch and Flemish painters, or 19th-century Impressionism (of which the museum possesses the largest collection in Germany).
