The Charles V Wall is a 16th-century defensive curtain wall that forms part of the fortifications of the British Overseas Territory of Gibraltar. 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.
Giovan Giacomo Paleari Fratino (1520–1586), known as El Fratin or Il Fratino, was a military engineer who served the Spanish Emperor Charles V, and then his son Philip II of Spain. He is known for having designed the first Martello tower as well as many other fortifications.
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.
The Montagu Bastion is one of many bastions which were designed to protect Gibraltar. Montagu was joined to Orange Bastion by a curtain wall known as Montagu Curtain and this bastion was protected by the Montagu Counterguard.
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.
Wellington Front is a fortification in the British Overseas Territory of Gibraltar. It was built in 1840 on a site established by the Spanish in 1618.
Hesse's Demi Bastion is a demi-bastion in the British Overseas Territory of Gibraltar. It is part of the Northern Defences of Gibraltar. The bastion forms a link in a chain of fortifications which ascend the lower north-west slopes of the Rock of Gibraltar, below the King's Lines Battery and Bombproof Battery. The Moorish Castle's Tower of Homage is at the top of the same incline.
Jumper's Bastion may refer to one of two adjacent bastions in the British Overseas Territory of Gibraltar. They were both created in 1785 on the sites of previous constructions and named for a British Captain who was one on the first on shore during the Capture of Gibraltar in 1704.

The fortifications of Gibraltar have made the Rock of Gibraltar and its environs "probably the most fought over and most densely fortified place in Europe, and probably, therefore, in the world", as Field Marshal Sir John Chapple has put it. 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 Lines of Contravallation of Gibraltar, known in English as the "Spanish Lines", were a set of fortifications built by the Spanish across the northern part of the isthmus linking Spain with Gibraltar. They later gave their name to the Spanish town of La Línea de la Concepción. The Lines were constructed after 1730 to establish a defensive barrier across the peninsula, with the aim of preventing any British incursions, and to serve as a base for fresh Spanish attempts to retake Gibraltar. They played an important role in the Great Siege of Gibraltar between 1779 and 1783 when they supported the unsuccessful French and Spanish assault on the British-held fortress. The siege was ended after the lines of contravallation were attacked by British and Dutch forces under the command of the Governor of Gibraltar,General Augustus Eliot. The attack caused the Spanish forces to retreat and abandon the fortifications and the combined British led forces virtually destroyed all the spanish gun batteries and the enemy cannon and munitions either captured or destroyed. This attack is still commemorated to this day and is known as 'Sortie Day'.
