Castell de Cabrera is a late 14th-century fortress located on the island of Cabrera in the Balearic Islands, standing as a hexagonal structure at 72 meters elevation commanding the natural harbor's entrance. Built to defend against pirate incursions threatening island navigation and commerce, the fortress was first referenced in 1410 when tower keepers claimed payment from the Viceroy of Mallorca. The castle's strategic position provided commanding surveillance of naval traffic, making it one of the Balearic Islands' most strategically significant defenses; guards were among the highest paid in the region. In 1550 Turkish commander Dragut attacked and partially destroyed the fortress, and it later served as a prison for French soldiers during the 1808 War of Independence. Today the castle summit offers panoramic views of the picturesque countryside, nearby coastline, and surrounding waters, with a small museum enhancing the visitor experience.
