Gråen

About

Gråen is a small artificial Swedish island in Øresund, originally constructed during the 18th century both in order to protect Landskrona harbour and for military reasons related to the nearby Landskrona Citadel. A smaller allotments area is located on the island, and access is only by boat. Most of its 50 acres is a bird sanctuary and there are strong trespassing rules between 15 March and 1 August. Only a very few authorised ornithologists are allowed inside the sanctuary during the breeding season (the allotment area is excluded).
