Alte Nationalgalerie

The Greek temple–style Old National Gallery (smb.museum; €16) is a three-story showcase of 19th-century European art. To get a sense of the period's virtuosity, pay special attention to the moody landscapes by Romantic heart-throb Caspar David Friedrich, the epic canvases by Franz Krüger and Adolf Menzel glorifying Prussia, the gothic fantasies of Karl Friedrich Schinkel, and the sprinkling of works by French and German impressionists.
