Fort I in Kaliningrad, Military fortress in Bol'shoe Isakovo, Russia.
Fort I forms part of an extensive defensive ring that stretches across 8 kilometers from central Kaliningrad with a 20-meter-wide moat surrounding its perimeter.
The construction of Fort I, completed in 1892, incorporated financial resources from France following their defeat in the Franco-German War of 1870-1871.
The fortress contains over 1,200 rooms including military quarters, dining halls, hospitals, and command centers that reflect 19th-century Prussian military architecture.
The fortress maintains its structural integrity despite the passage of time, though visitors currently do not have access to explore its interior spaces.
Each section of the fortress follows a symmetrical hexagonal design, measuring 360 meters in width and 180 meters in depth.
