The Kazimierzowski Palace used to house the Warsaw Lyceum, where the young Chopin was one of the pupils. He began attending the school at the age of thirteen, having been immediately admitted to the fourth grade. He had previously been home-schooled.
The Kazimierzowski Palace was built in the first half of the 17th century as the summer residence of King Jan Kazimierz. For thirty years, it housed the renowned School of Chivalry (Szkoła Rycerska) founded by Stanisław August, the last king of Poland.
Today, the building is owned by the University of Warsaw.
