Throughout history, the island of Mallorca has been concerned with the defense of its coast lines. Naturally, if ever an enemy was approaching, the attack would have come from the sea.
During the 20th century, as many as a dozen artillery battery defense installations have been based around the Badia de Palma alone, including Sant Carles, Torre d’en Pou and Cap Blanc (Cabo Blanco, see photo) etc. The military installations came under the responsibility of the Cuerpo del Regimiento de Artillería de Costa de Mallorca.
The installations of Cap Blanc were abandoned in 1996, even though the premises still remain the property of the Spanish Ministerio de Defensa. In close proximity to the Cap Blanc military installations, there are also those of Cap Regana, Cap Roig (also known as Punta Llobera) and Cala Carril (also known as Ensenada del Carril), all of which are in equal disuse now.
Some of the Cap Blanc artillery guns or cannons are now on exhibit at the Museu Militar de la Fortalesa de Sant Carles. Quite impressive, really.
