This Belgian commemorative stamp, issued in 1967, marks the 700th anniversary of the founding of the city of Ostend (Oostende). The design features the iconic Ostend Casino-Kursaal, an architectural landmark symbolizing the city's seaside elegance and cultural vitality. Rendered in delicate brown and sky-blue tones, it reflects both historical pride and artistic precision. The city’s coat of arms appears in the upper right corner, while “1267–1967” commemorates seven centuries of Ostend’s maritime and civic heritage. A fine example of Belgium’s tradition of architectural and historical philately.
