OSOWIEC FORTRESS IN THE BIEBRZA NATIONAL park
IMMERSE IN HISTORY
Poland’s largest national park, the Biebrza National Park, is the domain of Nature. It has also witnessed some momentous historical events. The Park is home to the remains of the mighty Osowiec Fortress, erected by the Tsar to withhold German attacks. The fortress proved invincible and has never been conquered.
Today many bird species nest on the fortifications, and in winter the vaults provide shelter for an enormous colony of bats. You can only tour the fortress with a guide. If you want to peek in every corner of this huge fortification complex, it might take you as long as 8 hours!
You can find a list of licensed, English speaking tour guides on the Biebrza National Park website.
