King's Bastion is a coastal bastion on the western front of the fortifications of the British overseas territory of Gibraltar, protruding from the Line Wall Curtain. It is located between Line Wall Road and Queensway and overlooks the Bay of Gibraltar . It played a crucial role in defending The Rock during the Great Siege of Gibraltar. In more recent history the bastion was converted into a generating station which powered Gibraltar's electricity needs. Today it continues to serve the community as Gibraltar's leisure centre.
