Explore the history of Gibraltar on this 2.5-hour sightseeing tour by small 6-8 seater air-conditioned minibus. Travel back in time at Gibraltar's most famous sights, such as the 100 Ton Gun, manufactured by Sir W G Armstrong at Newcastle-Upon-Tyne in 1870. Only 12 guns were built, and this is the only one left still in good condition. The 32.65-foot-long 17.72 inch rifled muzzle loader was capable of firing up to 8 miles. Continue to Europa Point, the southernmost point in Gibraltar, with its Trinity House Lighthouse and impressive views across the Straits of Gibraltar to the northern coast of Africa. Your next stop is the spectacular St. Michael’s Cave, which was converted into a military hospital during World War II. It has a wealth of history that dates back tens of thousands of years, and today it is used as a concert hall, with one of the best natural auditoriums with great acoustics. Continue to Apes Den to meet the famous Barbary Apes, the only apes still roaming wild in Europe, in their natural habitat. Next, visit the Great Siege Tunnels, carved out by the Merchant Marines to defend Gibraltar during the Great Siege of 1779 to 1783. Finally, go the imposing Moorish Castle, built by the Moors in after their conquest of Gibraltar in the eighth century. The tour ends in Casemates Square, ideal if you wish to carry on shopping or relax at a local restaurant.
