The Skyhigh site was originally a World War II gun site. There are five old gun emplacements each surrounded by its own blast walls. Seventy five metres away from the emplacements is the main magazine where the Ack Ack shells were stored. Each emplacement has its own sub magazine, which supplied each individual gun. The arrangement is ideal for Skyhigh’s purposes. Each emplacement now houses process buildings which are licensed for up to 12 people to work on explosives. Outside the emplacements are process buildings for non-explosive work plus the licensed packing shed.
