The northern border of the island is formed by the waters of Port Channel (Gdańsk), while the southern border is a branch of the Vistula called Martwa Wisła.
Ostrow Island belongs to Gdańska Stocznia Remontowa, a prosperous industrial enterprise, and Stocznia Gdańsk, a group of Stocznia Gdynia.
During World War II, Nazi Germany operated a subcamp of the Stutthof concentration camp on the island from October 1944 to March 1945, in which they subjected around 100 Jewish women to forced labour.[1]
