This elegant trio from Deutsche Bundespost Berlin belongs to the Castles and Palaces (Burgen und Schlösser) definitive series, issued between 1987 and 1990. The 60 Pf stamp depicts the Marksburg Castle on the Rhine, one of the best-preserved medieval castles in Germany. The 200 Pf shows Schloss Bürresheim in the Eifel region, noted for its mix of Romanesque and Baroque architecture. The 230 Pf features Burg Lichtenberg, a sprawling fortress complex in the Palatinate. These minimalist line-engraved designs capture the timeless grandeur of Germany’s historic landmarks and are favorites among definitive collectors.
