This was initially called St George’s Spur on plans dated march 1901. The battery has an underground section with a large Shell Store on the north side, and the Cartridge Store and Royal Artillery Store on the south. The works were subsequently upgraded with shell lifts and other automation.
In 1904 some crew shelters were built to the rear of the battery which included an officers shelter and two shelter for men.
The gun barrel at Spur Battery was upgraded after World War I. In addition, its mount was changed from a Mark V to a Mark VII in 1935. This entailed increasing the armour and modernising the control system, and resulted in improvement of loading, elevation, and traverse. The specifications of the weapon included a combined weight for the gun and its mounting of 204 tons, with the weight of the barrel 28 tons. Each shell weighed 380 lbs; individual charges were 109 lbs. The 9.2-inch gun had a muzzle velocity of 2,700 ft/sec and fired 2–3 rounds/minute. The range of the gun was 29,600 yds.
