A late 18th-century English landscape garden created by Princess Helena Radziwiłłowa between 1778 and 1821, about 5 kilometres east of Łowicz. The park contains Gothic and Classical garden follies, artificial ruins, a temple of Diana, grottos, and a lake — all designed as a Romantic meditation on time, death, and nature. It was one of the most celebrated landscape gardens in Poland when it was created.
The park has suffered considerable neglect over the centuries and is now only partially restored, but this adds to rather than detracts from its atmosphere — genuine ruins rather than maintained reconstructions. Worth combining with a visit to the nearby Nieborów palace and gardens (a well-preserved Baroque manor with excellent gardens, about 4 kilometres away).
