Lord Airey's Shelter is a subterranean military shelter in the British Overseas Territory of Gibraltar. It is located near the southern end of the Upper Rock Nature Reserve, adjacent to Lord Airey's Battery. It was named after the Governor of Gibraltar, General Sir Richard Airey. The tunnel system for the shelter was chosen as the site for the highly classified, Second World War military operation known as Operation Tracer.

The Rock of Gibraltar (from the Arabic name Jabal Ṭāriq جبل طارق) is a monolithic limestone promontory located in the British territory of Gibraltar, near the southwestern tip of Europe on the Iberian Peninsula, and near the entrance to the Mediterranean. It is 426 m (1,398 ft) high. Most of the Rock's upper area is covered by a nature reserve, which is home to around 300 Barbary macaques. These macaques, as well as a labyrinthine network of tunnels, attract many tourists each year. The Rock of Gibraltar, one of the two traditional Pillars of Hercules, was known to the Romans as Mons Calpe, the other pillar being Mons Abila, either Monte Hacho or Jebel Musa on the African side of the Strait. According to ancient myths fostered by the Greeks and the Phoenicians, and later perpetuated by the Romans, the two points marked the limit to the known world, although the Phoenicians had actually sailed beyond this point into the Atlantic, both northward and southward.The Mediterranean Sea surrounds Gibraltar.

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.

O'Hara's Tower was a watchtower in the British Overseas Territory of Gibraltar. It was located at the highest point of the Rock of Gibraltar, at what is now O'Hara's Battery, near the southern end of the Upper Rock Nature Reserve. Initially known as St. George's Tower, it was constructed in the late 18th century on the order of then Lieutenant Governor Charles O'Hara, under the presumption that it would be useful in observing the enemy at the Port of Cadiz. Not only was it unsuccessful; it was struck by lightning shortly after it was built, and remained in ruins for much of the 19th century until its demolition in 1888. Formerly referred to as St. George's Tower, it came to be known as O'Hara's Tower or, frequently, O'Hara's Folly.

Dudley Ward Way is a road tunnel through the south-eastern part of the Rock of Gibraltar. It is named after Sir Alfred Dudley Ward, Governor of Gibraltar from 8 June 1962 to 5 August 1965. The road running through the tunnel links the eastern side of The Rock (including Catalan Bay and Sandy Bay) via Sir Herbert Miles Road, with Europa Point, at the southern tip of Gibraltar via Europa Advance Road.

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.
