A view across Shark Island to Luderitz's port. Shark Island, which is now joined to the mainland, was once home to the world's first extermination camp/concentration camp. Between 1905 and 1907 the Germans interned prisoners caught during the Nama-German war on the island. It was reported that by April 1907, 1032 of the Nama prisoners had died. It is believed that as many as 80% of the prisoners sent to the island died.
