Detached Mole, Gibraltar Harbour

The South Mole is a breakwater located in the southern section of Gibraltar Harbour, in the British Overseas Territory of Gibraltar, at the southern end of the Iberian Peninsula. Previously known as the New Mole and New Mole Extension, the South Mole, with the rest of harbour, is just north of the east entrance to the Strait of Gibraltar.

The Gibraltar South Mole Lighthouse is one of several lighthouses in Gibraltar, a British Overseas Territory at the south end of the Iberian Peninsula.

The lighthouse remains operational and is positioned west of the Rock of Gibraltar, on the South Mole at Gibraltar Harbour. It is operated by the Gibraltar Port Authority.

Alexandra Battery is a coastal artillery battery in the British Overseas Territory of Gibraltar. It was constructed at the neck of the South Mole (originally the New Mole) to enfilade the coastal fortifications of Gibraltar. The battery stood on the site of several previous fortifications; it was built over the New Mole Battery, which was itself constructed on the site of an old Spanish fort in front of the Tuerto Tower.The battery owed its construction to the recommendations of an 1868 report by Colonel (later General) William Jervois. He proposed that a new battery should be constructed on the site to house a RML 12.5 inches (320 mm) 38 ton gun – at the time, the heaviest rifled muzzle-loading gun in the British Army's inventory – in a casemate protected by an iron shield. It was named after Alexandra of Denmark, the wife of Edward, Prince of Wales (later King Edward VII). He laid the foundation stone in 1876 and the battery was finished two years later, but it was already out of date by 1902, and by 1906 it had been converted into accommodation casemates. The slide and the mounting were subsequently scrapped but the 12.5 inch gun was moved to near Engineer Battery and finally relocated to Harding's Battery in 2013. In 1940, a QF 2-pounder Pom-pom gun was installed on the top of the casemates to protect the South Mole and a Bofors 40 mm gun was installed in 1941 to provide anti-aircraft defence. The battery still exists and is reportedly in a relatively good condition.

Ragged Staff Flank is a masonry fortification on the South Front of Gibraltar's fortifications. It continues the line of the South Bastion's seaward face across the South Front ditch, then turns to form a flanking position facing south along the coastal fortifications leading to the New Mole. The Ragged Staff Gates were situated in the middle of the flank, leading to the Ordnance Wharf that was located where the Dockyard North Gate used to stand. A defended enclosure stood behind the gate, secured by the Ragged Staff Guardhouse. The flank position had three embrasures in its parapet but only mounted two 24-pdr guns in 1779, though these were replaced by 32-pdrs under the rearmament plan of 1859.

Ragged Staff Gates are a set of city gates in the British Overseas Territory of Gibraltar. They are located between South Bastion and Ragged Staff Guard, opposite the Navy Boat Sheds.

The South Bastion was part of the fortifications of Gibraltar, protecting the western base of the Charles V Wall. It was originally built by Spanish military engineers, later improved by the British. The South Bastion stands at the south end of the Line Wall Curtain which defends the town from attack from the Bay of Gibraltar. Another curtain wall runs east from the bastion to the base of a precipice. This wall is pierced by the Southport Gates, guarded by the South Bastion and the Flat Bastion on either side.
