I Fort

I Fort is a military fortification in Kaunas with red brick walls and concrete structures built into the surrounding terrain. Parts of the structure now lie beneath water, creating an unusual landscape where nature and ruins coexist.

Construction began in 1882 as part of the Russian Empire's defensive network, forming the western edge of the Kaunas Fortress system. Intense German artillery fire during World War I caused severe damage and led to portions becoming flooded.

The fortress grounds now serve as a protected habitat for bat populations, contributing to local wildlife conservation efforts.

The fort is partially accessible through guided tours, though winter visits are limited to protect the bat colonies living there. The warmer months offer better conditions for exploring, as pathways are more manageable.

Bat populations now inhabit the flooded chambers and stone surfaces of the fort, making it an unintended wildlife sanctuary. This unexpected coexistence of war ruins and animal protection gives the place an unusual character.
