The manor-park complex in Nienadowa (Dubiecko municipality) is one of the better preserved residence-farm complexes in southeastern Poland. It consists of a strict representative center delineated by the extent of the landscaped park, within the boundaries of which are located: the classicist manor house building and outbuildings – both built just after 1809. – as well as a slightly later cordegarde built before 1853. An extensive area to the north of them is occupied by a complex of farm buildings. We can consider Antoni Dembiński – the owner of the complex at the turn of the 18th/19th century – as the creator of the preserved establishment. Nienadowa passed into the hands of the Dembiński family in 1726 and remained their property until 1947.
