Prince Ferdinand's Battery
Prince Ferdinand's Battery is a former British artillery position high on the Rock of Gibraltar, now better known to visitors as the Apes' Den — the most popular spot to observe Gibraltar's famous Barbary macaques in their natural habitat. Set within the Upper Rock Nature Reserve at the base of the Charles V Wall, the site blends military history with a unique wildlife experience found nowhere else in Europe. Beyond the macaques, the battery retains traces of its martial past, including the remarkable Healy's Mortar — an 18th-century experimental weapon cut directly into the living rock. Panoramic views sweep across the Strait of Gibraltar, North Africa, and the Iberian coast, making this one of the most rewarding stops on the Upper Rock.
