This commemorative stamp celebrates 750 years of Regensburg as a Free Imperial City, a status granted in the medieval Holy Roman Empire. The design features intricate Gothic-style artwork, including sculpted figures and the symbolic crossed keys—associated with Saint Peter and the city’s historic coat of arms. The architectural framing reflects Regensburg’s rich medieval heritage, one of the best-preserved in Germany. The muted tones and detailed engraving style give the stamp a classic historical aesthetic. It is a fine example of Germany’s cultural and architectural commemoratives.
