Gorham's Cave (Spanish: Cueva de Gorham, pronounced [ɡoˈɾam]) is a sea-level cave in the British overseas territory of Gibraltar. Though not a sea cave, it is often mistaken for one. Considered to be one of the last known habitations of the Neanderthals in Europe, the cave gives its name to the Gorham's Cave complex, which is a combination of four distinct caves of such importance that they are combined into a UNESCO World Heritage Site, the only one in Gibraltar. The three other caves are Vanguard Cave, Hyaena Cave, and Bennett's Cave.It is located at Governor's Beach on the southeastern face of the Rock of Gibraltar. When first inhabited some 55,000 years ago, it would have been approximately 5 km (3.1 mi) from the shore, but, due to changes in sea level, it is now only a few metres from the Mediterranean Sea.

Levant Cave is a cave in the British Overseas Territory of Gibraltar. Together with Tina's Fissure and George's Bottom Cave, Levant Cave is part of a close group of three caves at the southern end of the Upper Rock Nature Reserve.The "Levant series of caves" consists of Levant Cave, George's Bottom Cave, and Gibbon's Cave. Levant Cave was discovered in a similar way to Lower St. Michael's Cave as they were both discovered during military tunnelling. In the case of Levant Cave the Royal Engineers were tunnelling to build a command centre for the 9.2 inch gun at Levant Battery. The tunnelling damaged the cave but some attractive formations remain.

Tina's Fissure is a cave in the British Overseas Territory of Gibraltar. Tina's Fissure, George's Bottom Cave and Levant Cave are a close group of three caves at the southern end of the Upper Rock Nature Reserve.

George's Bottom Cave is a cave in the British Overseas Territory of Gibraltar. This together with Tina's Fissure and Levant Cave are a close group of three caves at the southern end of the Upper Rock Nature Reserve.The existence of George's Bottom Cave was suspected on 27 November 1965 when the Gibraltar Cave Research Group found a small hole in the Rock of Gibraltar near Spur Battery, 310 metres (1,020 ft) above sea level. As the group could feel a draught from this hole they suspected it was the entrance to a cave and they arranged to have a large boulder moved to reveal a larger but still small entrance. The cave was named after George Palao of the Gibraltar Museum. Having entered the cave, visitors find that the passage is tight, which necessitates crawling at some points. Crawling in is made no easier by the cave coral which together with the curtains, columns, straws, and helictites create a variety of limestone formations. However, the cave has six different levels which contain a wide variety of formations in numerous chambers and fissures.

Martin's Cave is a cave in the British Overseas Territory of Gibraltar. It opens on the eastern cliffs of the Rock of Gibraltar, below its summit at O'Hara's Battery. It is an ancient sea cave, though it is now located over 700 feet (210 m) above the shore of the Mediterranean Sea. It is only accessible because Martin's Path was constructed.

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.
