Muzeum Ziemiaństwa (the Museum of the Landed Gentry) in Dobrzyca is housed in a classicist palace designed for Augustyn Gorzeński by the Warsaw architect Stanisław Zawadzki. The shell of the palace, with its giant portico, was completed in 1795, and the interiors are decorated with wall paintings attributed to artists including Antoni Smuglewicz. The residence is surrounded by a historic park. We prepared a mobile app for Android and iOS phones as well as an audioguide system. The recordings lead visitors through the palace and tell the story of the residence and its owners. The audio guide is available in Polish, English and German.
