The Monument of December 1970 Victims is one of the youngest Szczecin pedestals. The angel designed and sculpted by Prof. Czesław Dźwigaj was unveiled on 28th August 2005. At the foot of the sculpture there are plaques with surnames of the victims of those events as well as initiators of erecting the monument and commemorative inscriptions. The monument commemorates the workers' rebellion, also known as ‘December 70' or the ‘December events'. The reason for the strikes and demonstrations was the rise in prices of food, introduced on 12th December 1970. The main centres of December 70 rebellion were cities in the north of Poland (Gdańsk, Gdynia, Szczecin, Elbląg). Here shipyards were the biggest workplace rebellion centres. As a result of brutal suppression of the workers' demonstrations by the communist authorities in Szczecin fourteen people were killed (in Szczecin, Gdynia, Gdańsk and Elbląg 39 people were killed in total). Workers of the Szczecin Shipyard joined the ranks of the protesters on 17th December 1970. The army and militia opened fire to the crowd of many thousands of demonstrators within the city when the latter set fire to the building of the Provincial Committee of the Polish Working Class Party (PZPR). Sixteen people were killed, including teenagers and those who accidentally found themselves at the protest scene.
