For centuries, Działdowo lay where states and cultures met. This history is told by the Borderland Museum (Muzeum Pogranicza), housed in the town hall and the Teutonic castle. Visitors can explore an interactive exhibition on the State of the Teutonic Order and the display “Działdowo – the town and people of the old borderland”, which presents the fortunes and achievements of the local community. The app with an audio guide, available on the App Store and Google Play, lets you tour the museum using your own smartphone. With it, you can explore one room after another at your own pace and better understand how the borderland shaped the town and its inhabitants.
