3 May, 2019 an installation «memory penetration» was opened in the museum of Temirtau city to the Victory Day in the Great Patriotic War 1941- 1945 years.

The installation was the result of the city action "Letters of Memory", announced by the museum on May 9, 2018. The participants of the action created the front letters - triangles and signed them with their name in memory of the generation who gave their lives in the fight against fascism. This memory permeates human hearts, time and space. It creates an unbreakable link between the modern generation and our heroic ancestors. 683 people took part in the «Letters of Memory» event. The promotion is still ongoing.
