In more recent history the bastion was converted into a generating station which powered Gibraltar's electricity needs.

King's Bastion is located at the junction of Queensway and Reclamation Road on the western side of the British overseas territory of Gibraltar.

"[5][6] The bastion was designed by Lieutenant colonel Sir William Green, Chief Engineer of the Soldier Artificer Company which later became the Corps.

[7] Less than a decade later, in 1782, King's Bastion served ably as the command post in the defence against the attacks of the French and Spanish during the Great Siege of Gibraltar.

The turn of the century was remarkable for the reclamation of land in front of King's Bastion, as part of the new dockyard.

[7] A plaque (pictured below) installed on the northern façade of King's Bastion acknowledges the role of General George Augustus Eliott, 1st Baron Heathfield, the Governor of Gibraltar, in his command during the Great Siege.

In addition, Major General Sir Robert Boyd was at his request interred inside a vault at the bastion's base, which he had included at the time of construction.

[6] A memorial stone was placed within the King's Chapel but the marble stone in the King's Bastion read: "Within the walls of this bastion are deposited the mortal remains of the late General Sir Robert Boyd, K.B., governor of this fortress, who died on 13 May 1794, aged 84 years.

Oil storage and administration offices, among other facilities required for the day-to-day running of the station were housed within the vaults of the bastion itself.

Facilities include, ice skating, cinemas, bowling, arcade games, fitness gym, al fresco dining, youth lounge, internet area and a nightclub.
