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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
