The collection of the Painting Gallery was born out of the joint passion of the Great Elector (1620-88) and of Frederick the Great (1712-86). It now represents one of the world's major collections of 13C-18C European art. Over 1,000 works of art are displayed in the building designed by architects Heinz Hilmer and Christoph Sattler. The section devoted to Flemish and Dutch masters of the 17C (Baroque) is particularly noteworthy.
