O’Hara’s Battery is an coastal defence artillery battery in the British Overseas Territory of Gibraltar is at an incredible height of about 426 meters (1398 feet), at the highest peak, near the southern end of the Upper Rock Nature Reserve in the Upper Battery area, which also includes Lord Airey’s battery and battery spur.
It was built in 1890 on the former site of a watchtower, built by Governor Charles O’Hara, known as “the madness of O’Hara”.
Named in honor of General Charles O’Hara, Governor of Gibraltar from 1795-1802, it was initially the place where the attempt to build a watchtower failed, from which the garrison could monitor any suspected enemy in the port of Cadiz, at a surprising distance of 100 km. Upon failing in its purpose, the garrison began to call the tower, the O’Hara Madness.
The first 6-inch 6″ (152.4mm) cannon was mounted in 1890, but was replaced in 1901 by a 9.2″ (152.4mm) -inch cannon with a range of 29,000 yards (26 km), aided to some extent by its height above sea level.The battery was in use during World War II and was last fired during training exercises in 1976.
O’Hara’s Battery is listed with the Gibraltar Heritage Trust.
