Fort V of Kaunas Fortress Fortification

Fort V in Kaunas city, near Kaunas Lagoon, was built in 1882–1889 and has undergone little reconstruction.

The fort is in the shape of an asymmetrical elongated hexagon. There are barracks in the rear part, and a counterscarp wall runs along the defensive ditch. On top of the defensive rampart were artillery and infantry defensive positions. Anti-assault gun shelters were located under the outer rampart. Inside the territory, under the inner artillery defensive rampart, there are warehouses for combat supplies, which are connected by underground galleries with posterns to the semi-caponiers and caponier intended for the defense of the defensive ditch. The outer ditch is surrounded by a surviving escarpment wall with riflemen's positions. An additional battery with a separate ammunition depot was formed on the right flank of the fort.

During the First World War, when the Germans stormed the Kaunas Fortress, Fort V was left out of the main attack and could only contribute little to the fortress's defense. While retreating, the fort's defenders blew up the gunpowder and ammunition depot, as well as the underground gallery leading from the barracks to this depot.

​During the interwar period, the fort housed a Lithuanian army weapons workshop and a ballistics range for testing ammunition. From November 16, 1939, the 7th camp for interned Polish soldiers was briefly established here.

During the Soviet era, a technical division of the anti-aircraft defense regiment was deployed, the barracks were adapted to truck garages, the territory was paved with concrete slabs, additional premises for anti-aircraft missiles and fuel storage were built. The division guarded strategic objects in Kaunas, including the Kaunas HPP.

Currently, the fortifications are being maintained, and a large part of the territory is occupied by an active leisure sports club.
