For an experience of the 19th century's artistic excellence, be sure to visit the Old National Gallery. This grandiose Greek temple–style three-storey building displays a wide range of European art from that period. Admire the wistful landscapes of Romantic artist Caspar David Friedrich, be awed by the grandiose works of Franz Krüger and Adolf Menzel, who both celebrated Prussia in their art, marvel at the Gothic fantasies of Karl Friedrich Schinkel, and take pleasure in the French and German impressionist pieces.
