The present manor in Kośmin was erected in the years 1907–11, on the site of the former building dating from the first half of the 19^th century, retaining its initial location in the valley of the Wieprz River picturesquely meandering beneath. In her novel Trembowla, Zofia Kossak begins the description of the place as follows, “The manor, the farmyard and the plum house were located within a loop created by the Wieprz River, capriciously meandering through the plains.”

The old growth of trees from the former park has been preserved next to the manor. It consists of the European White Elms, Small-leaved Limes, Norway Maples, European Ashes, and Eastern White Pines, among others. The Canadian Poplar alley growing along the drive to the manor that ends with the thick spruce lane have been recently planted. The park has also retained the spatial relation with the picturesque river landscape and the village. As of 1945, the palace of the former owners of the Kośmin estate houses the Zofia Kossak Elementary School. The Memorial Chamber dedicated to the school patron located inside is open to public. The colourful figures painted on the classroom doors attract attention. This is how the characters from Zofia Kossak’s book, Kłopoty Kacperka, góreckiego skrzata [The Troubles of Kacper the Mountain Gnome] were illustrated.
