Raikuun salpa-asema

The fortification complex includes three reinforced concrete bunkers and two types of anti-tank stone barriers along a 1.5-kilometer trail through forest terrain.

The Raikuu fortifications were constructed between 1940 and 1941 during World War II as part of Finland's defensive Salpa Line against potential military invasions.

The site demonstrates Finnish military engineering expertise through its integration of natural terrain features with constructed defenses along the historical Swedish-Russian border.

Automatic lighting systems in two bunkers activate for 15 minutes to help visitors navigate the underground structures during their exploration of the site.

The fortification incorporates natural stone-edged canals that connect Puruvesi and Orivesi lakes, creating a combined system of water barriers and military structures.
