100 Ton Gun of Gibraltar
100 Ton Gun is one of the attractions in Gibraltar honoring its military heritage. Located at Napier of Magdala Battery, this historic artillery is one of the original twelve guns manufactured by the British in 1870. Gibraltar has two in possession but only one, this piece in Napier Battery, was kept in mint condition. Its features depicted the strength of the British Naval supremacy and dominance in using steam engines not just for locomotives but for warfare as well.
During its time, this 17.72-inch Rifled Muzzle loader was a landmark assemblage of arms and weaponry. Its barrel measures some 32 feet, with a firing range that extended up to 8 miles. Steam engine technology powered the gun through hydraulics, which took at least 3 hours to complete in order to operate the firearm.
The 100 Ton Gun required about 450 pounds of black prism gunpowder that can pierce through the toughest wrought iron as thick as 24 inches. It was capable of firing one round every four minutes, operated by a battalion of 35 men.
It was in September 2002 that the historic piece of artillery was last test fired during a Gibraltar-Malta conference. The occasion exhibited the gun’s firepower rocking through Gibraltar along with the simultaneous firing of its counterpart in the Maltese shores.
The entrance to the Upper Rock Nature Reserve includes the visite to the 100 Ton Gun.
