Pałac w Zarzeczu, Palace complex in Zarzecze, Poland.

Pałac w Zarzeczu is a palace building featuring a circular rotunda supported by Doric columns and displaying classical architectural details from the early 1800s. The structure extends into designed gardens with symmetrical pathways and planted areas that connect the main building to the surrounding green spaces.

The palace was built between 1807 and 1810 for Magdalena Morska of the Dzieduszycki family, to a design by Piotr Aigner; the adjoining wing was designed by Georg Szuster. After Morska's death in 1847 the estate passed to her brother Józef Kalasanty Dzieduszycki and then to Count Włodzimierz Dzieduszycki. It remained the family seat until 1944, sheltering insurgents and refugees, including Father Stefan Wyszyński in 1942. A museum opened in the palace on 23 April 2008.

The palace houses furnishings and personal objects from the 19th century that document how the Dzieduszycki family lived and their place in Polish society. Visitors can see the rooms arranged as they were during the family's time here.

The palace stands on the southern edge of a hill, with the orangery and wooden porch linking it to the two-storey outbuilding. The roughly 9-hectare romantic park, laid out by Magdalena Morska and finished by 1840, has uneven ground around the hilltop. Look for the 200-year-old London plane in front of the palace and the Amur cork trees near the orangery.

The park was laid out by Magdalena Morska herself, and work on its roughly 9 hectares lasted until 1840. She kept the old oaks of the former oak wood as part of the composition. Near the palace stand a 200-year-old London plane and, by the orangery, an American tulip tree.
