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 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 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.
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.
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.

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.
King's Bastion is a coastal bastion on the western front of the fortifications of the British overseas territory of Gibraltar, protruding from the Line Wall Curtain. It is located between Line Wall Road and Queensway and overlooks the Bay of Gibraltar. It played a crucial role in defending The Rock during the Great Siege of Gibraltar. In more recent history the bastion was converted into a generating station which powered Gibraltar's electricity needs. Today it continues to serve the community as Gibraltar's leisure centre.

The Gibraltar peninsula, located at the far southern end of Iberia, has great strategic importance as a result of its position by the Strait of Gibraltar where the Mediterranean Sea meets the Atlantic Ocean. It has repeatedly been contested between European and North African powers and has endured fourteen sieges since it was first settled in the 11th century. The peninsula's occupants – Moors, Spanish, and British – have built successive layers of fortifications and defences including walls, bastions, casemates, gun batteries, magazines, tunnels and galleries. At their peak in 1865, the fortifications housed around 681 guns mounted in 110 batteries and positions, guarding all land and sea approaches to Gibraltar. The fortifications continued to be in military use until as late as the 1970s and by the time tunnelling ceased in the late 1960s, over 34 miles (55 km) of galleries had been dug in an area of only 2.6 square miles (6.7 km2).
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 cannons 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 Queen's Lines are a set of fortified lines, part of the fortifications of Gibraltar, situated on the lower slopes of the north-west face of the Rock of Gibraltar. They occupy a natural ledge which overlooks the landward entrance to Gibraltar and were an extension to the north-east of the King's Lines. They run from a natural fault called the Orillon to a cliff above the modern Laguna Estate, which stands on the site of the Inundation, an artificial lake created to obstruct landward access to Gibraltar. The Prince's Lines run immediately behind and above them on a higher ledge. All three of the Lines were constructed to enfilade attackers approaching Gibraltar's Landport Front from the landward direction.
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.
