In 1764, Ujazdów became the property of King Stanisław II Augustus. The monarch first set about rebuilding Ujazdów Castle which he chose as his summer residence. Work was begun in the castle's forefield, where a series of straight paths converging at circles was laid out. The remodelling of the old Ujazdów Castle, which received an additional storey and new wings, dragged on without producing the expected results. The king became discouraged, abandoned further work and shifted his attention to the surrounding gardens.
