2) A barn of the sumikowo-łątkowa construction with coal corners (the so-called fishtail) and a pitched roof. It had a hinged entrance gate and its exit gate could be moved with the use of rockers. The barn dates back to the year 1784. It was brought to Gosławice from the village of Czepów, the commune of Uniejów.
3) A windmill of the "koźlak" type dating back to the end of the 19th century with complete original furnishings, brought from the village of Bochlewo, the commune of Kazimierz Biskupi.
