The Wilanów Palace is one of the most precious monuments of Polish Baroque. Built for King Jan III Sobieski at the end of the 17th century and gradually expanded by successive owners, it represents an unusual combination of a traditional Polish court with an Italian rural villa and a French chateau. The interiors of the palace, with their original design and decadent furniture, represent three style eras. The oldest, Baroque royal apartments are located in the main building, while the south wing represents an 18th century style and the more modern rooms, decorated by the Potocki family in the 19th century, are in the northern wing. The Crimson Hall, the Cabinet of the Etruscans, the Lapidary and the pre-Gallery Cabinet are all part of the historical museum founded in 1805.
The first floor houses the Polish Portrait Gallery of Works from the 16th to the 19th centuries, with portraits of kings, representatives of great aristocratic families, distinguished Poles and cultural figures. Among them, characteristic Polish coffin portraits and Sarmatian Counterfeits are also displayed.
The two-level garden is the 'frame' of Wilanów Palace, and somehow manages to combine a stylish Baroque garden, a romantic English-Chinese park, an English landscape park and a neo-Renaissance garden into a stylish and harmonious whole. The eastern part of the grounds are surrounded by a lake, the southern end of which has a cascading water feature, and the whole of the garden is decorated with sculptures, fountains and miniature samples of architecture.
