Stocznia Gdańska (since 2006 Stocznia Gdańśk SA) is one of the biggest Polish shipyards. It is located in Gdańsk, upon the lower bank of Martwa Wisła and on Ostrów. During its operation, the shipyard constructed over 1000 fully equipped ocean-going ships, container ships, passenger ships and sailing ships. The events of December 1970 – putting down the protests and killing three shipyard workers – took place at the premises of the shipyard. The site is also the cradle of Solidarity – it witnessed the signing of the agreements of August 1980. In 1996 the shipyard went into liquidation; subsequently Stocznia Gdańska - Grupa Stoczni Gdynia SA, and since 2006 - Stocznia Gdańśk SA was established on the basis of the old shipyard.
