Westerplatte, situated at the entrance to the harbour and just a few kilometres from the city of Gdañsk, is where World War II broke out on 1 September 1939. The Polish garrison held out against the attack for seven days before surrendering to the German forces, and the site is now a memorial to the defenders. Sights at Westerplatte include a small museum, some of the ruins left from the shelling and a massive monument that towers above the area.
