The contract for the construction of the Seventh Fort was signed on 7 July 1883 between the contractor reserve lieutenant colonel Nikolay Shevtsov and Fortress Engineering Board.
During World War I, 6-inch 45 caliber Canet gun was installed near the Fort, which successfully fired at the enemy's trenches in Germaniškiai village area.
The goal of this temporary unit was adoption of military assets left by Germans for needs of the newly established Lithuanian Army.
Interior partitions in the former fort kitchen on the right wing of the barracks were removed to create the office of archive's director.
The next day, the decision had been made during the meeting of the Lithuanian Provisional Government to set up a Jewish concentration camp in the Seventh Fort [citation needed].
There had been appointed a newly formed Lithuanian partisan groupTautinio Darbo Apsaugos Batalionas (known as TDA) for camp protection and murder of its prisoners.
The famous people among the victims were rabbi Elchonon Wasserman (1875–1941) and Lithuanian poet Vytautas Montvila (1902–1941).
Pioneer unit engaged in restoration of bridges blown during World War II was based in the Seventh Fort.
During this period, the historic fort suffered much damage:[citation needed] the defensive ditch was filed with trash and dirt, building facades were damaged, drainage system was destroyed, left artillery yard was paved with asphalt, garages for auto vehicles storage were built.
After the Russian Army left Lithuania in 1993, the Seventh Fort was transferred to the Lithuanian National Defence Volunteer Forces (KASP).
One of the first projects carried out in the fort was scientific and field research, restoration of casemates, and removal of asphalt paving.
Additionally, low-value garages were demolished, drainage system was restored which allowed the rear caponier to become accessible once again.
