Wartime History
During the war, a gun battery and positions were constructed on the eastern side of the island. During the 1950s, the western side of the island was used as a leper colony. Today, the island is empty and uninhabited.

Gemo Island Battery (Gemo Battery)
In mid-April, 1944, the Australian 8th Army Troops Company / Royal Engineers built a gun battery facing east. It accommodated two 6 pound guns, with a concrete ammunition storage area and bunker behind it. They used building materials transported to the island by barge and a small trolley system. Also, two pillboxes on the beach. The battery and pillboxes are still present to this day. The position also included a small wharf, that is gone.
