to Polish history and culture. Meanwhile, special architectural designing offices, under Jan Dąbrowski, Piotr Biegański and Jan Zachwatowicz, drew up blueprints for restoring the framework of the building and furnishing the historical rooms. The decision to start work was postponed several times, but was finally taken on 20 January 1971. A Civic Committee was set up. Amid universal applause it was decided to rebuild the castle from voluntary contributions. Both, in Poland and abroad fund-raising committees were set up. By May 1975 the Fund had already reached the 500 million zlotys. By the same date more than a thousand valuable works of art had been given to the Castle by numerous Poles resident both in Poland and abroad. Official representatives of other countries have likewise presented to the Castle works of art of great artistic and historic value. Today The imposing façade, built of brick, is long and faces the Castle Square. At each end of the façade stands a square tower with a bulbous spire.

The Jagiellonian Rooms These rooms, which belonged to the residence of Sigismund Augustus, are now host to a number of portraits of the Jagiellon dynasty, a royal dynasty originating in Lithuania that reigned in some Central European countries between the 14th and 16th century. In 2011 the Jagiellonian Rooms were re-arranged to house the modern Gallery of Painting, Sculpture and Decorative Arts. The Houses of Parliament From the 16th century onwards, Polish democracy started here. In 1573, amendments to the constitution of the Polish–Lithuanian Commonwealth were written here, with great religious tolerance. Also, during the Deluge in 1652, the liberum veto was established in these rooms, although not carried out until 1669. In 1791, the May Constitution, Europe's first modern codified national constitution as well
