Jalkavakimuseo, the Infantry Museum, gives Mikkeli another strong military-history stop in a city closely associated with Finland's wartime command. Exhibits cover infantry equipment, uniforms, and the experience of soldiers across Finland's modern conflicts.
It pairs naturally with the Headquarters Museum, but the focus is different: less command-room strategy, more ground-level army history. Check opening times outside summer, when smaller Finnish museums may keep limited hours.
