The archaeological committee values Linnankasarmi quite highly as a traditional military area and prehistoric site because the medieval town of Hämeenlinna has once been here and its remains are still under the barrack yard.

On the ground floor of the main building the birth of our artillery centuries ago is on display.

A muzzleloader called Helvig, a cannon dating back to the War of Finland 1808-1809 is one of the guns worth mentioning.

Special branches, such as artillery intelligence, communications and survey activities are placed on this floor.

On display is also the uniform of Väinö Myllyrinne, the largest Finnish soldier ever at 226 centimeters some 7 foot and 5 inches tall.

The third floor displays the life of the Marshal of Finland Gustaf Mannerheim, and for example the honorary gun, a Finnish 105 H 37 light howitzer on which gun carriage Mannerheim was escorted to the eternal rest in the winter 1951 is on display.

Also is shown the life in the Finnish army after the Second World War and the technological development of artillery is also given special consideration.

there is no other museum outside Russia with a collection on Russian and Soviet artillery equipment as exhaustive as this.

On the honorary place in the gun yard, with the flag of the Artillery Museum as a color guard, there is the funeral gun of the Artillery General, Mannerheim Cross Knight Vilho Nenonen, a Finnish 105 H 37 light howitzer.

A new special exhibition "Artillery themed tin toys" opened in April 2010.
