Fort Dłubnia

Fort Dłubnia is a military fort in Kraków with a trapezoidal shape and deep dry moats surrounding its perimeter. The structure includes casemate galleries positioned at the corners and a two-story brick building protected by earthen embankments.

The fort was built between 1892 and 1896 as part of Kraków's fortress system and originally contained four howitzer towers and two cannon towers. It served the Austro-Hungarian military's territorial defense strategy in the region.

During the interwar period, Polish specialists worked at the fort on decrypting the German Enigma code through radio intelligence operations.

The site can be visited during daylight hours, and visitors should wear sturdy shoes since the ground is uneven and the moats require navigation. Tours are organized through a local museum that provides additional context and information.

The armored towers were partially demolished in the 1970s to salvage metal, which caused permanent cracks throughout the structure. These damages remain visible at various points across the fort today.
