Princess Caroline's Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located at the northern end of the Upper Rock Nature Reserve, at the junction of Willis's Road and Queen's Road. The nearby Princess Anne's Battery is often mistakenly referred to as Princess Caroline's Battery. The latter was built in 1732 and named after Princess Caroline, the daughter of King George II. Princess Caroline's Battery was updated in 1905, and a 6 inch Mark VII gun was mounted above the magazine. Later, the battery was decommissioned and the gun removed. The underground magazine is now home to the Military Heritage Centre, which includes the Memorial Chamber.
Princess Anne's Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located on Willis's Plateau at the northern end of the Upper Rock Nature Reserve, above Princess Caroline's Battery. It was named after Anne, Princess Royal and Princess of Orange, the eldest daughter of George II. However, its name is often confused with those of other batteries in the area. In 1732, guns were first mounted on the battery, which also saw action during the Great Siege of Gibraltar. Princess Anne's Battery was updated in the nineteenth and twentieth centuries, with the latter modernisation entailing the installation of four QF 5.25 inch guns with both anti-aircraft and coastal defence capabilities. The battery was manned into the early 1980s, after which it was decommissioned. The guns were refurbished in the early twenty-first century, and represent the world's only intact battery of 5.25 inch anti-aircraft guns. Princess Anne's Battery is listed with the Gibraltar Heritage Trust.
O'Hara's Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located at the highest point of the Rock of Gibraltar, near the southern end of the Upper Rock Nature Reserve, in close proximity to Lord Airey's Battery. It was constructed in 1890 at the former site of a watchtower that had earned the name O'Hara's Folly. The battery and tower were both named after the Governor of Gibraltar Charles O'Hara. The first gun mounted on the battery was a 6-inch breech loading gun, which was replaced with a 9.2 inch Mark X BL gun in 1901. The battery was in use during World War II and was last fired during training exercises in 1976. O'Hara's Battery has been refurbished and is open to the public. The battery and its associated works are listed with the Gibraltar Heritage Trust.
Princess Amelia's Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located on Willis's Plateau at the northern end of the Upper Rock Nature Reserve, adjacent to Gun No. 4 of Princess Anne's Battery. It was named after Princess Amelia of Great Britain, the second daughter of George II. It was formerly referred to as the 2nd Willis's Battery. The plateau and its batteries had previously been named after an artillery officer by the name of Willis who was outstanding during the capture of Gibraltar in 1704. Princess Amelia's Battery saw action during the Great Siege of Gibraltar, during which it sustained substantial damage. Little remains of the original site, aside from two derelict buildings. The battery is listed with the Gibraltar Heritage Trust.
Lord Airey's Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located near the southern end of the Upper Rock Nature Reserve, just north of O'Hara's Battery. It was named after the Governor of Gibraltar, General Sir Richard Airey. Construction of the battery was completed in 1891. The first gun mounted on the battery was a 6-inch breech loading gun, which was replaced with a 9.2-inch Mark X BL gun by 1900. The gun at the battery was last fired in the 1970s. In 1997, it was discovered that Lord Airey's Shelter, adjacent to Lord Airey's Battery, was the site chosen for a covert World War II operation that entailed construction of a cave complex in the Rock of Gibraltar, to serve as an observation post. The battery is listed with the Gibraltar Heritage Trust.
Princess Royal's Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located on Willis's Plateau at the northern end of the Upper Rock Nature Reserve, just southeast of Princess Anne's Battery. Formerly known as Willis' Battery, and later, Queen Anne's Battery or Queen's Battery, it was renamed in the late 18th century after Charlotte, Princess Royal, the eldest daughter of George III. The battery was active from the early 18th century until at least the mid-20th century. However, it has been decommissioned and guns are no longer present. Princess Royal's Battery is listed with the Gibraltar Heritage Trust.
Breakneck Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located on Ministry of Defence property at the Upper Rock Nature Reserve, north of Lord Airey's Battery. It is one of a dozen batteries in Gibraltar that had 9.2-inch (233.7 mm) guns installed around the turn of the twentieth century. The emplacement features a 9.2-inch Mark X breech-loading gun on a Mark V mounting. The battery was refurbished by 10 Signal Regiment in 2012 and 2016 whilst being on Ceremonial duties whilst the Gibraltar Regiment where on exercise and is one of three surviving 9.2-inch gun emplacements at the Upper Ridge of the Rock of Gibraltar. By the late twentieth century, the 9.2-inch guns in Gibraltar, Bermuda, Portugal, South Africa, and Australia were the remaining examples of an emplacement that at one point had been mounted at strategic locations across the British Empire.
Spur Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located in the Upper Battery area of the southern end of the Upper Rock Nature Reserve, just southwest of O'Hara's Battery. A 9.2-inch Mark X breech-loading gun was mounted on the emplacement in 1902, with improvements made to the battery after World War I. In 1981 the 9.2-inch gun at Spur Battery was dismantled and transferred to the Imperial War Museum in Duxford, England, for preservation. The operation was known as Project Vitello.
Operation Tracer was a secret Second World War military operation in Gibraltar, a British Overseas Territory and military base. The impetus for the plan was the 1940 scheme by Germany to capture Gibraltar, code-named Operation Felix. Operation Tracer was the brainchild of Rear Admiral John Henry Godfrey, the Director of the Naval Intelligence Division of the Admiralty.
Levant Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located on Windmill Hill, at the southern end of the Upper Rock Nature Reserve, below observation post Fire Control South. It was named after the Levanter cloud, below which it perched, giving it an unobstructed view. Construction started in 1901 and, by 1903, a 9.2-inch Mark X breech-loading gun had been mounted. The battery was decommissioned in the 1970s and the gun was later removed, to rest in a scrap yard. A community group has been formed to garner support for the gun's recovery and restoration.
Green's Lodge Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located on the North Face of the Rock of Gibraltar at the northern end of the Upper Rock Nature Reserve, above Farringdon's Battery. Also known as the Superior Battery, it was named after General Sir William Green, who served in Gibraltar for twenty-two years, most of them as the chief engineer of Gibraltar. In 1776, guns were first mounted on the battery, which also saw action during the Great Siege of Gibraltar. The emplacement also underwent reconstruction in the early and mid twentieth century. Green's Lodge Battery is listed with the Gibraltar Heritage Trust.
Rock Gun Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located on the North Face of the Rock of Gibraltar at the northern end of the Upper Rock Nature Reserve, above Green's Lodge Battery. The emplacement on Middle Hill is at the northern summit of the Rock. It was constructed during the Great Siege of Gibraltar, due to its advantageous position and the success of the gun at Green's Lodge Battery. It was used effectively during the Great Siege and was rebuilt during the Second World War. During the mid-twentieth century, the Ministry of Defence began to use the site as an aerial farm, which was then refurbished in 1958. The Rock Gun Battery and the Middle Hill Battery were closed to the public for decades. In 2005, the radio farm was closed and the Ministry of Defence withdrew from most of the area, transferring it to the Government of Gibraltar. However, the summit, the site of the Rock Gun Battery, continues to be under MOD authority.
Middle Hill is a hill in the British Overseas Territory of Gibraltar. It is located at the northern end of the Upper Rock Nature Reserve. It figured prominently in the early history of the 1704 siege of Gibraltar by the Spanish and French. The artillery battery at Middle Hill had been constructed by 1727 and was active for more than two centuries. In the mid twentieth century, Middle Hill transitioned to use as an aerial farm for the Ministry of Defence. The radio farm was refurbished in 1958. About 1970, the Princess Caroline's Battery Group of Barbary macaques were moved to Middle Hill, where they were provisioned at a group of derelict buildings that were part of the battery complex. In 2005, much of Middle Hill was transferred from the Ministry of Defence to the Government of Gibraltar, and is now managed by the Gibraltar Ornithological and Natural History Society.
Middle Hill Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located on Middle Hill, at the northeastern end of the Upper Rock Nature Reserve, just south of Green's Lodge Battery and Rock Gun Battery. The emplacement dates to 1727, when a single gun was mounted. By the turn of the twentieth century, six 10-inch rifled muzzle-loading guns were present at Middle Hill Battery. Other buildings documented at that time as part of the battery complex included the Nursery Hut and the Middle Hill Group, the latter a cluster of buildings which perched on the cliff edge. An anti-aircraft Bofors gun had been installed at the battery by the Second World War. After the war, the area transitioned to use as a Ministry of Defence aerial farm. In 2005, the battery and surrounding area were transferred to the Government of Gibraltar. The site is now managed by the Gibraltar Ornithological and Natural History Society.
The Gibraltar Caving Group is an organisation based in the British Overseas Territory of Gibraltar. It forms the Caves and Cliffs Section of the Gibraltar Ornithological and Natural History Society. The group of skilled cavers and climbers has multiple roles, engaging in cave exploration and research, avian rescue, and rare plant discovery. It performs surveys and clears areas with limited access. However, it is perhaps most well known for the discovery that four of its members made in December 1996. While exploring tunnels in the southern portion of the Rock of Gibraltar, they found the entrance to Operation Tracer, also known colloquially as Stay Behind Cave. Rumours of a covert World War II observation post had circulated in Gibraltar for decades. The Gibraltar Caving Group continued its exploration and evaluation of the facility under the auspices of the Gibraltar Museum.
Brigadier Sir Richard Gambier-Parry, was a British military officer who served in both the army and the air force during World War I. He remained in military service post-war, but then entered into civilian life for more than a decade. In 1938, he was recruited by the head of the Secret Intelligence Service. Gambier-Parry led the Communications Section of the SIS during World War II, and assembled a clandestine wireless network that connected the United Kingdom with SIS agents in many countries, as well as helping to create the SIS resistance network in Britain. During the war, he was also recruited by the Director of British Naval Intelligence to serve as the radio consultant for Operation Tracer in Gibraltar. Post-war, he ran a network of secret listening stations.
Surgeon Lieutenant-Commander Bruce Cooper was a native of Castle Eden, England. He obtained his medical degree from Durham University. Early in his career, he tended to coalminers and joined the Royal Naval Volunteer Reserve. The physician served with distinction in the early period of the Second World War and was mentioned in despatches. In 1941, he was recruited for a highly classified mission, Operation Tracer. In the event that Gibraltar was taken by the Axis powers, he was to be sealed into a secret chamber in the Rock of Gibraltar with five other men for about a year and report the movements of enemy vessels. Over a period of two years, the secret complex was completed and the team assembled and trained. However, the mission was never activated. Cooper returned to England and served in both civilian and military capacities. The location of the secret chamber remained a mystery for decades, but was finally discovered in 1997. However, many questions remained, including the identity of the team members. Upon Cooper's return to Gibraltar in 2008, he confirmed that the cave in question was that which had been destined for himself and his five colleagues. Dr Cooper was the last surviving team member of Operation Tracer in Gibraltar.
Coptic Cave is a sea cave in the British Overseas Territory of Gibraltar. The cave was intended to be used as a decoy to protect Operation Tracer. This was a plan to leave behind spies should the British lose control of the Rock of Gibraltar in World War II.
Beefsteak Cave is a cave in the British Overseas Territory of Gibraltar. It is located in the south of the Rock, between Europa Point and Windmill Hill.
