Issued by Germany (Deutsche Bundespost), this 20 Pfennig definitive stamp depicts the historic Lorsch Abbey, one of Germany’s most important Carolingian architectural monuments. The design highlights the famous Torhalle (gatehouse), an outstanding survival of early medieval architecture. Part of the mid-1960s German Buildings & Monuments definitive series, the stamp reflects post-war cultural preservation themes. Its clean single-color engraving style makes it a classic example of West German definitive aesthetics. A popular collectible among architecture, UNESCO heritage, and Germany thematic collectors.
