The Great Siege Tunnels, situated towards the top of the Upper Rock, are one of Gibraltar’s star tourist attractions. Dug by hand during the 1789-83 Great Siege of Gibraltar – an unsuccessful attempt by Spanish and French forces to seize the territory from Britain – their purpose was to facilitate the installation of big guns on an otherwise inaccessible part of the Rock called “The Notch”. Extreme military pressure hastened their construction, and in just five weeks more than 25 metres of a 2.4 sq metre tunnel had been built.
During Word War II, the network of subterranean corridors dug during the Great Siege were expanded in order to accommodate a 16,000-strong garrison and all of its supplies. A further 17 miles of tunnels were added to the existing seven, the main purpose of which was to connect up a new military base on the south-east of Gibraltar with established bases on the west. Two major north-south arteries were also added – the Great North Road and Fosse Way – both of which run effectively the entire length of the Rock.

Gibraltar’s 100-ton gun is one of the territory’s key attractions and overlooks Rosia Bay at the Napier of Magdala Battery. In service between 1877-1906, it was originally one of four manufactured: two were sent to Malta and two to Gibraltar, of which this is the only one that remains here (the other surviving gun can be visited in Malta). In fact weighing 103 tons, it could only fire once every four minutes and its range was a relatively limited 3.7 miles – but at that distance it could still blast through 15 inches of steel.

Situated in the Princess Caroline Battery just beneath Gibraltar’s Moorish castle, the Military Heritage Centre displays a range of artefacts relating to the Battery’s military history from the 18th century on, in particular from the Great Siege of 1789-83. In addition to items such as shells and weapons used in the defense of Gibraltar from its many assailants over the centuries, there is a Memorial Chamber in which the regiments deployed to fight for the territory are remembered. Best reached by an undemanding half-an-hour walk downhill from the top cable car station.
Gibraltar is famous for its exquisite handcrafted glassware, so the place to head if you want to learn all about this local speciality is Gibraltar Crystal, located on the terrace-lined Casemates Square. Once you’ve strolled around the small but fascinating exhibition space – which features panels explaining the centuries-old techniques and tools used in glassblowing – you can see the art performed in front of your very eyes (for free) in the adjacent workshop, where three masters of the trade ply their craft. The resulting glassware is sold in the attached shop, in which you can also have your choice customised for no extra charge.
