O'Hara's Tower, Military watchtower on Rock of Gibraltar, British Territory
The tower stood at 426 meters altitude at the highest point of the Rock of Gibraltar, near the southern end of the Upper Rock Nature Reserve.
General Charles O'Hara ordered the construction of this watchtower in 1787 to monitor Spanish fleet activities at the Port of Cadiz.
The garrison named it O'Hara's Folly after discovering that the Port of Cadiz remained invisible due to intervening mountain ranges.
The structure was demolished in 1888 through target practice by HMS Wasp crew, making way for O'Hara's Battery with its 6-inch breech-loading gun.
A sentinel lost his life when lightning struck the tower during a storm shortly after its construction, leaving it in ruins for many years.
