The Presidential Palace is currently the seat of the president of the Republic of Poland. During the pre-uprising period (before 1831), the palace was the seat of the government of the Kingdom of Poland, then of the Warsaw Gubernatorial Government; in the years of the 2nd Republic and of the Polish People's Republic it was the seat of the Council of Ministers. The Warsaw Pact Treaty was signed in this building in 1955, and in 1989 it was here that the Round Table negotiations - the non-violent takeover of power - took place.
