Our company, in a consortium with Unibep S.A., has had the honor to participate in the construction of this place, so important for Poland and its history. On the main square, an altar wall was placed, on which a raised relief was sandblasted – over 160,000 letters that make up the names of the victims. In front of the wall, a big monolithic altar was placed. The altar wall is composed of 10 blocks with a height of 4.5 m and the base of 1.2×0.4 m and its total weight is 80 tons.
