The Central Ordnance Munitions Depot (Chinese: 壽臣山軍火庫) was constructed in the late 1930s by British for the World War II to combat the Japanese Invasion as well as to store arms and ammunition for the defence of Hong Kong. The British used "Little Hong Kong", name for the fishing village town of Aberdeen, as a “code name” to refer to the military site and therefore confuse Japanese spies in the local community before the Japanese invasion.
