Bouda|Osówka: Go Underground

Set out on the Military Underground Trail and discover the unique underground complexes of the Bouda Artillery Fortress and the Osówka Underground City. During your visit, you will complete themed tasks, earn badges for finished routes and gradually unlock new challenges. Once you have visited both sites, you will receive the special No Borders badge. The app offers: a themed game for visitors, tasks to complete right during your tour, badges to collect for individual routes, interesting facts about military underground sites, a link between the Czech and Polish parts of the trail. The app was created as part of the Discovering Border Fortifications project, which connects the Bouda Artillery Fortress and the Osówka Underground City. The project is co-financed by the European Union under the Interreg Czechia–Poland 2021–2027 Programme from the European Regional Development Fund.
