Wrights Hill Fortress
Engineering Work (eg road, bridge, sawmill, dam)
Wrights Hill Fortress in Wellington was one of three long range coastal batteries built in New Zealand during World War Two. The other two fortresses were located in the environs of Auckland:
- Waiheke Island
- Whangaparoa Peninsula.
The Wrights Hill site was first identified in 1935 but authority for the work was not given until March 1942. Engineering contractors, Downers were awarded the contract for the construction work although as manpower problems arose later in the project Public Works Department workmen also became involved. The construction involved 620 metres (m) of interconnected tunnels leading to three gun emplacements for three 9.2 inch guns. The site was independently powered by two 185 horsepower Ruston & Hornsby diesel generators to manoeuvre the guns and auxiliary generators to supply lighting and air conditioning.
Two guns were installed by the Army in 1944, but the order for the third was cancelled as the situation in the Pacific war improved. Each gun weighed 135 tons – the barrels alone weighing 28 tons. The two installed guns were not fired during the war but were satisfactorily fired (as far as the Army were concerned) after the war (in 1946 and 1947) with three rounds each. Local damage to windows resulted from the firing. The guns could fire a 172 kilogram (kg) shell up to 30 kilometre across Cook Strait towards Tory channel, or up as far as Plimmerton. Each shell was about 1 m long and was propelled by two half charges of 28 kg of cordite.
The fortress was closed in the late 1950’s, the guns sold for scrap in 1960 and the site abandoned. The fortress was rescued by the Karori Lions Club and opened for the public for the first time on ANZAC Day 1989. Subsequently the Wrights Hill Fortress Restoration Society was formed and has been actively restoring the site to near its former state.
