In 1921 the League of Nations granted Poland the right to install an ammunition depot near Gdańsk, and station a garrison there. Despite some objections from the Free City, this right was confirmed in 1925, where the location was finally agreed on with the choice of Westerplatte. Westerplatte was primarily separated from the New Port of the Free City of Danzig by the harbour channel, with only a small pier connecting them to the mainland; the Polish-held part of the Westerplatte was separated from the territory of Danzig by a brick wall. The depot was completed in November 1925 and became operational in January 1926. The Polish garrison's size was set at 88 soldiers, and Poland was not allowed to construct fortifications.
