Sidon Sea Castle - 35 piastre

This definitive airmail stamp (Poste Aérienne) celebrates Lebanon's ancient coastal defenses and maritime heritage by highlighting the historic Sidon Sea Castle (Sidon - Le Château de la Mer). The fine dark brown engraving illustrates the medieval stone fortress surrounded by breaking waves, connected to the mainland by its iconic fortified stone bridge, while a twin-engine transport aircraft cruises through the hazy sky overhead. This multi-layered composition carries a profound message of defensive strength, historical continuity, and modern transport progression. Issued by the Lebanese Republic (Republique Libanaise), the design weaves an emblem of Phoenician and medieval maritime defense into the fabric of daily mid-century postal communications.
