It belongs to the district of Vorpommern-Rügen in northeast Mecklenburg-Vorpommern in Germany.
Due to the solitary location of its only farmstead, the island was also given the nickname Ostsee-Hallig ("Baltic Sea Hallig" – a hallig being a desolate, marshy, North Sea island off the Jutland coast).
Today the island is part of the municipality of Groß Mohrdorf and is a nature reserve belonging to the West Pomeranian Lagoon Area National Park.
South of the island is the Grabow bodden and to the north lies the Baltic Sea.
As a result of increasing siltation of the inlet at the eastern tip of the Zingst, the Große Werder became a peninsula (as at summer 2006).
