Here you also find the Three Crosses Monument (also called the "Solidarity Monument") at Solidarity Square, that symbolizes the workers struggle and is a memorial for the ones who died during the strikes. The Solidarity movement (Solidarnosc) was created by Walesa to protest against the poor working conditions for the workers at the Lenin Shipyard (today Gdansk Shipyard) in the early 1970s. In 1980 the big strikes at the shipyard led to protests all over Eastern Europe, and finally lead to the fall of the communist regime in Poland. Solidarity later became a political party, with Lech Walesa as a leader. Between 1990 and 95 he became the president of Poland.
