Perched dramatically above the Rhine's broad sweep, Schloss Stolzenfels commands its forested hillside in this atmospheric copper-gravure (Kupfertiefdruck) postcard from the 1930s — its Gothic Revival towers and battlements rising against a sky of billowing clouds, the river curving silver below. Stolzenfels, near Koblenz, was rebuilt in the 1830s–1840s for Crown Prince Friedrich Wilhelm of Prussia in a romantic neo-Gothic style by Karl Friedrich Schinkel and his circle, becoming one of the Rhine's most celebrated castles. The publisher, Karl Rud. Bremer & Co. of Cologne, was a leading producer of high-quality German topographical cards in the interwar period. The reverse is blank and unposted, suggesting this was purchased as a souvenir, likely by a traveler on one of the famous Rhine steamship tours of the era.
