The initial funding for Woolpack Battery came in 1898. The Battery was to be armed with two modern 6-inch Mark VII guns (introduced in 1989). The building work commenced in August 1898 and was completed by May 1901. Woolpack Battery was built as a joint project with Steval Battery and Woolpack (Greystone) Barracks.
The Battery was built along the ‘Dispersed’ or Twydall profile model, the intention being to make to batteries hard to observe by maintaining a low profile and natural camouflage. The battery was oval in layout, about 85 metres (275 feet) by 40 metres (120 feet) with a dry ditch perimeter protected by barbed wire. The two-gun pits are located centrally, about 30 metres (100 feet) apart with underground magazines and shelters between them. A Battery Command Post with DRF and telephone room, was built to the rear of the gun line. An underground passage runs from the magazine to casemates under the BCP.
There is an old smooth bore battery, down on the shore line below the 6-inch battery, which is also know as Woolpack Battery.
The underground works are presently used as accommodation for staff from a nearby hotel.
