The palace in Falenty is an early Baroque palace from the first half of the 17th century, built around 1620 by Zygmunt Opacki, the chamberlain of Warsaw. Located in Falenty, in the Raszyn commune, it is surrounded by a landscape park.
The palace hosted, among others, Kings Zygmunt III and Władysław IV, as well as Queen Ludwika Maria Gonzaga in March 1646. After being destroyed during the Swedish Deluge, the palace was renovated in 1717 by Franciszek Jan Załuski. In the 18th century, it underwent further reconstructions, including in 1787, when the modernization was carried out by the architect Szymon Bogumił Zug. At that time, the palace was visited by King Stanisław August Poniatowski.
After various changes of ownership, the palace passed to Jan August Spiski, who rebuilt the estate, and later to Maria Przeździecka and her husband, Aleksander. In the years 1852–1857, another reconstruction took place, under the direction of the Italian architect Franciszek Maria Lanci. After World War II, the palace became the seat of state institutions, including the Supreme Audit Office and the Council of State.
Currently, the palace houses the Institute of Technology and Life Sciences and the Higher School of Entrepreneurship and Regional Development.
