Bou Regreg Estuary
The Bou Regreg Estuary forms the natural boundary separating the twin historic cities of Rabat and Salé along Morocco’s Atlantic coast. Flanked by ancient fortifications, grand minarets, and bustling medinas, the river mouth has historically served as a vital maritime entrance and a geographic landmark for navigation.
Issued in 1955 as a definitive airmail value (MAROC / المغرب / POSTE AÉRIENNE), this 200-franc stamp (ESTUAIRE du BOU REGREG) presents an elevated panorama designed by A. Delpy and engraved by Munier. The composition contrasts historic Moroccan heritage with modern aviation, featuring the traditional rooftops and minaret of the medina overlooking the expansive estuary and ocean bay, while a four-engine Lockheed Constellation airliner flies overhead.
