Arkadia - is a small (today with about 250 inhabitants) village (originally named "Łupia"), located on the Skierniewka River in the Łódź Voivodeship, in the Łowicz poviat, in the Nieborów commune. In 1777, Helena Radziwiłłowa née Przeździecka, the wife of Michał Hieronim Radziwiłł, the then owner of Nieborów, bought it and ordered an English-style garden and park complex to be created, according to the design of Szymon Bogumił Zug (other architects also participated in the design).
In the park with an area of approx. 15 hectares, apart from the river, ponds, trees and bushes, you can see stylized ("antique" and "Gothic") buildings, some of which have been preserved to our times in a good condition - the "Temple of Diana", the "Grotto Sibyl", "Greek Arch", "Murgrabi's House", "Aqueduct", etc. The park, which today, like the nearby park and palace complex in Nieborów, is a branch of the National Museum in Warsaw, can be visited from May to September from 10:00 to dusk.
