The timber framed storage buildings and laboratories are unique and are the last remaining from the War. It is one of the major fixed installations built during World War II and is the largest of its type in the Northern Territory
. The Depot site provides valuable evidence of the impact of World War II on the Territory, and the remaining structures on site have a powerful visual effect.
Snake Creek Armament Depot is one of the Northern Territory
’s most extensive extant World War II military sites. It was constructed between 1943 and 1945 after the Navy identified the need for a semi-remote magazine. The design included a road system and a 2.85 km rail loop from the North Australia
Railway, an ammunition storage area capable of storing 3,500 tons of high explosives, and related facilities. A total of sixty-nine structures were built, some into the hill
slope and some entirely above ground. It appears that the whole complex was camouflaged against aerial observation. The RAAF controlled the facility between 1953 and 1962,The facility fell into disuse in the 1970s and subsequently the site was vandalised and much material removed. There is one large building still standing today, that was a Bomb Inspection Laboratory built in the mid 1950's.
