Boyen Fortress, Military fortress in Giżycko, Poland.
The fortress extends across a strategic isthmus between Lake Kisajno and Lake Niegocin, following a hexagonal layout with four entrance gates and walls stretching 2,303 meters.
King Frederick William IV ordered the construction of this Prussian fortress between 1844 and 1856, requiring 3,000 soldiers to complete the massive military complex.
The fortress contains six bastions, with three named after General Hermann von Boyen and three decorated with symbols from his family crest.
Visitors can explore the fortress grounds through guided tours that explain the military architecture and examine the preserved defensive structures throughout the year.
During World War II, the fortress contained a German intelligence center where captured Russian officers received training to fight for the Third Reich.
