The palace-garden complex in Nieborów and the sentimental garden in Arkadia are the best-
preserved examples in Poland of old rural magnate residences. Its unique and perfectly preserved elements are the gardens, diversified in form and vegetation, originating from different periods, which together with the residential and farm buildings and landscape architecture create an architectural and garden layout of outstanding compositional, landscape, natural, architectural and artistic value. The most outstanding planners, architects, painters as well as builders and craftsmen worked on the construction and extension of the mansion, among them Szymon Bogumił Zug, Enrico Ittar, Pierre Norblin and many others.
Helena Radziwiłł née Przeździecka
The garden at ArBkadia is one of the first and best preserved gardens with a free composition in Poland. The original sentimental garden with a rich philosophical and literary programme, founded by Helena Radziwiłł née Przeździecka in 1778, was slowly transformed into a Romantic garden under her supervision. It was expanded and added to until her death in 1821. In subsequent periods, the garden was slightly transformed, and after World War II it underwent partial reconstruction.
