The Archaeological Reserve in Zawodzie is an open-air museum located on the site of a 10th-century medieval stronghold in Kalisz. It protects the remains of a significant Piast-era defensive settlement that served as a major regional administrative center. Visitors can view reconstructed early medieval defensive ramparts and timber housing structures. The site features the foundations of a Romanesque collegiate church built by Mieszko III the Old. Archaeological excavations here have unearthed thousands of artifacts, including weaponry, jewelry, and everyday items. The reserve functions as a branch of the District Museum of the Kalisz Region. It integrates educational exhibitions with preserved in-situ foundations. The landscape design incorporates elements representing the original topography of the Prosna river valley settlement. It is one of the most important archaeological sites in Poland for understanding early state formation.
