A strategic observation post since 1906
Erected in 1906 on Pomègues Island, the Pomègues Semaphore has played a crucial role in maritime surveillance of the port of Marseille. Replacing an earlier installation from 1864 located on the Cavaux plateau, it was moved to its current location in 1904 to optimize the monitoring of maritime approaches.
Architecture and technical characteristics
The building consists of a white structure housing the lookouts’ accommodations and an observation tower approximately 12 meters high, reaching 89 meters above sea level. The top floor, equipped with 360° bay windows, provided an essential panoramic view for detecting approaching ships.
Evolution and decommissioning
After decades of service, the semaphore was decommissioned on January 3, 1999. Since then, it has been rehabilitated and now houses the Conservatoire Études des Écosystèmes de Provence/Alpes du Sud (CEEP), which manages the natural areas of Frioul.
An iconic site to discover
Although the semaphore is not open for visits, Pomègues Island offers visitors hiking trails to explore its natural and historical riches. The military remains, the panoramas of the Mediterranean, and the local biodiversity make it a favored destination for history and nature enthusiasts.
To access the island, maritime shuttles provide regular connections from the Old Port of Marseille. Once there, it is recommended to wear good walking shoes, bring water, and use sun protection to fully enjoy this island getaway.
The Pomègues Semaphore remains a valuable testament to Marseille’s maritime heritage, offering a journey through time and history for all visitors curious to discover the secrets of the Phocean harbor.
