On the ground floor of the main building the birth of our artillery centuries ago is on display. The story proceeds from the War of Finland 1808-1809 through the period of Autonomy to the Finnish Civil War and to the Jäger Movement. A muzzleloader called Helvig, a cannon dating back to the War of Finland 1808-1809 is one of the guns worth mentioning. On the center passage of each floor there are projectiles from different periods and different guns.
