MEMMERT

'Memmert' is a small East Frisian island off the northern coast of Germany, with an area of 5.2 km². Memmert is uninhabited, with only one house on the island for wildlife-spotting purposes. Occasionally, some guests from the neighbouring islands visit Memmert for recreation. Memmert is officially a wildlife protected area.
Otto Leege, Sr. was the first, who set a foot on the island in 1888. The island plays an important role as a location in Erskine Childers's novel 'The Riddle of the Sands' (1903).
