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.

Queen's Road is the longest road in the British Overseas Territory of Gibraltar. It runs north-south through the Upper Rock Nature Reserve on the Rock of Gibraltar.

St. Michael's Cave lies off this road on Spur Battery Road. This is a large show cave featuring stalactites and stalagmites and an auditorium large enough to take orchestras. Also of note, apart from the nature reserve, are the Great Siege Tunnels at the northern end.

New St. Michael's Cave, also known as Lower St. Michael's Cave, is a cave system in the British Overseas Territory of Gibraltar. Unlike its namesake, St. Michael's Cave (proper), which has been known for over 2,000 years, this cave was discovered as recently as World War II. The cave was accidentally discovered during World War II, when in 1942 the Royal Engineers were blasting inside the Rock of Gibraltar so as to create an alternate entrance to the lower chambers of St. Michael's Cave, which had been prepared as an emergency hospital. The first sign was when their tunnelling appeared to create no rubble as it had fallen through the newly created opening into this previously undiscovered cave which may have remained sealed for some 20,000 years.The cave's chambers include examples of almost all known cave formations, including a lake nearly 40 yards (37 m) long containing an estimated 45,000 imperial gallons (200,000 L) of crystal-clear water. After the war, the cave and every visitor was supervised by the United Kingdom's Ministry of Defence, specifically the Royal Engineers. It was not until the 1970s that civilian guides were authorised. Within ten years, the guides were all civilians as the Gibraltar Tourist Board took over the cave's management from the military.Three-hour guided tours of the cave can be arranged, ending with viewing the underground lake.
