The Great Siege of Gibraltar was an unsuccessful attempt by Spain and France to capture Gibraltar from the British during the War of the American Revolution. It was the largest battle in the war by number of combatants.
The Great Siege Tunnels in the British Overseas Territory of Gibraltar, also known as the Upper Galleries, are a series of tunnels inside the northern end of the Rock of Gibraltar. They were dug out from the solid limestone by the British during the Great Siege of Gibraltar of the late 18th century.
The Charles V Wall is a 16th-century defensive curtain wall that forms part of the fortifications of the British Overseas Territory of Gibraltar. Originally called Muralla de San Benito, it was built in 1540 and strengthened in 1552 by Holy Roman Emperor Charles V. The wall remains largely intact and extends from South Bastion, which was once at the water's edge in the harbour, to the top ridge of the Rock of Gibraltar.
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.
The South Bastion was part of the fortifications of Gibraltar, protecting the western base of the Charles V Wall. It was originally built by Spanish military engineers, later improved by the British. The South Bastion stands at the south end of the Line Wall Curtain which defends the town from attack from the Bay of Gibraltar. Another curtain wall runs east from the bastion to the base of a precipice. This wall is pierced by the Southport Gates, guarded by the South Bastion and the Flat Bastion on either side.
The North Bastion, formerly the Baluarte San Pablo was part of the fortifications of Gibraltar, in the north of the peninsula, protecting the town against attack from the mainland of Spain. The bastion was based on the older Giralda tower, built in 1309. The bastion, with a mole that extended into the Bay of Gibraltar to the west and a curtain wall stretching to the Rock of Gibraltar on its east, was a key element in the defenses of the peninsula. After the British took Gibraltar in 1704 they further strengthened these fortifications, flooding the land in front and turning the curtain wall into the Grand Battery.
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.
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.
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.
General Sir William Green, 1st Baronet, of Marass, Kent was an officer in the British Army.
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.
Farringdon's Battery is an artillery battery in the British Overseas Territory of Gibraltar. Named after Sir Anthony Farrington, 1st Baronet, it is located above the north face of the Rock of Gibraltar within the Upper Rock Nature Reserve.
The Koehler Depressing Carriage was a novel type of gun carriage invented in 1782 by Lt George Frederick Koehler of the Royal Artillery. It was devised to enable cannon to be fired at a steeply downward-facing angle and was made necessary by the peculiar circumstances that the British Army faced during the Great Siege of Gibraltar between 1779–83. The carriage saw active service during the siege, when it was used to support the British counter-bombardment of Spanish and French artillery batteries during the successful defence of Gibraltar. Its success made Koehler famous and has been commemorated in a number of different forms over the last 230 years.
The Prince's Lines are part of the fortifications of Gibraltar, situated on the lower slopes of the north-west face of the Rock of Gibraltar. They are located at a height of about 70 feet (21 m) on a natural ledge above the Queen's Lines, overlooking the landward entrance to Gibraltar, and run from a natural fault called the Orillon to a cliff at the southern end of the isthmus linking Gibraltar with Spain. The lines face out across the modern Laguna Estate, which stands on the site of the Inundation, an artificial lake created to obstruct landward access to Gibraltar. They were constructed to enfilade attackers approaching Gibraltar's Landport Front from the landward direction.
Willis' Magazine is an 18th-century large magazine in the British Overseas Territory of Gibraltar. The magazine sits on a plateau with several artillery batteries.
Windmill Hill or Windmill Hill Flats is one of a pair of plateaux, known collectively as the Southern Plateaux, at the southern end of the British Overseas Territory of Gibraltar. It is located just to the south of the Rock of Gibraltar, which descends steeply to the plateau. Windmill Hill slopes down gently to the south with a height varying from 120 metres (390 ft) at the north end to 90 metres (300 ft) at the south end. It covers an area of about 19 hectares, though about 6 hectares at the north end is built over. The plateau is ringed to the south and east with a line of cliffs which descend to the second of the Southern Plateaux, Europa Flats, which is itself ringed by sea cliffs. Both plateaux are the product of marine erosion during the Quaternary period and subsequent tectonic uplift. Windmill Hill was originally on the shoreline and its cliffs were cut by the action of waves, before the ground was uplifted and the shoreline moved further out to the edge of what is now Europa Flats.
