Seat
By 1990 the decision-making center was situated in a building erected by obligatory subscription in the years 1948–1952. The shares, called ″little bricks" (in Polish "cegiełka") with nominal values of 50-, 100-, and 500 zlotys, were distributed among the entire society. The building was officially called the Party's House, and was also known as the White House or the House of Sheep. Since 1991 the Bank-Financial Center "New World" is located in this building. In 1991-2000 the Warsaw Stock Exchange had also its seat in this building.

From 1918 to 1931 a building with the seat of communication department was located in that place. Earlier – from the November Uprising to 1918 – there was also the seat of the Clearing-House.
