Admiralty Pier Gun Turret, a coastal artillery battery, was completed in the 1880s but never fired in anger. When built it was at the seaward end of the pier prior to a later pier extension. The hidden gems here are its original armaments: two Armstrong 16 inch Rifled Muzzle Loading guns each weighing 81 tons within a circular cast-iron turret. The guns, about 8 metres in length could fire a 1700 pound (771kg) shell nearly seven miles. They were the second largest Armstrong guns ever made and the only steam powered guns ever possessed by the coastal artillery in Britain.
