Located in Charzewicki Park, this building, alongside the palace, which is now a Regional Museum, is a reminder of Rozwadów's independence as a town. It is located in a park area, next to a tower in which estate officials once lived, and a few other buildings. The palace outbuilding is a three-story structure with a mansard roof, kept in the Neoclassical style. It is designed with a sense of symmetry and lightness and beautifully integrated into the landscape, which includes a 200-metres-long avenue lined with old red oaks. Currently, the building is used for restaurant and hotel purposes, which has restored its former glory after decades of devastation.
