With its characteristic shape and distinct colour, you will not mistake this building for any other. The Royal Castle is the former seat of the rulers of Poland. Go inside and look at the royal apartments and the Throne Room. Pay attention to original paintings by Rembrandt and the canvases of Bernardo Bellotto, known as Canaletto, which were used during the reconstruction of Warsaw after it was destroyed in World War II. See also the Senator’s Hall, in which in 1791 the 3rd May Constitution was passed – the first constitution in Europe and the second in the world. At the end, enter the beautifully reconstructed gardens: the upper garden situated on the castle slope and the lower one at its feet where the river used to flow in the seventeenth century. Carefully recreated in the style of the 1920s and 1930s, it not only complements the residence but it is also an ideal place to relax. The huge lawn, flower beds, fountains and mazes created from several-metre high hedges will give you a boost of energy for further sightseeing. If you have more time, stay a bit longer to see the charm of the garden in the glow of the illuminations after dark.
