The Presidential Palace is the elegant classicist latest version of a building that has stood on the Krakowskie Przedmieście site since 1643. Over the years, it has been rebuilt and remodeled many times. For its first 175 years, the palace was the private property of several aristocratic families. In 1791 it hosted the authors and advocates of the Constitution of May 3, 1791.
It was in 1818 that the palace began its ongoing career as a governmental structure, when it became the seat of the Viceroy of the Polish (Congress) Kingdom under Russian occupation. Following Poland's resurrection after World War I, in 1918, the building was taken over by the newly reconstituted Polish authorities and became the seat of the Council of Ministers. During World War II, it served the country's German occupiers as a Deutsches Haus and survived intact the 1944 Warsaw Uprising. After the war, it resumed its function as seat of the Polish Council of Ministers.
References:The Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains: the extraordinary system contains fifty-one fountains and nymphaeums, 398 spouts, 364 water jets, 64 waterfalls, and 220 basins, fed by 875 meters of canals, channels and cascades, and all working entirely by the force of gravity, without pumps. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
Tivoli had been a popular summer residence since ancient Roman times due to its altitude, cooler temperatures and its proximity to the Villa Hadriana, the summer residence of the Emperor Hadrian I.
The Villa was commissioned by Cardinal Ippolito II d'Este (1509-1572), second son of Alfonso I d'Este, the Duke of Ferrara and grandson of Pope Alexander VI, along with Lucrezia Borgia.
