Harparskog Line

Harparskog Line was the main defense station and military fortification built by the Finns after the Winter War of 1940–1941 on the border of Hanko.

Details
This line was not fully completed at the beginning of the Continuation War and remained unused at the Battle of Hanko. But the existence of this defense line made it possible to transfer troops from the Hanko area to the east in July–August 1941. Major Komola was responsible for the construction of this line. The line ran from Westerwick in Wetlax Brumarrow west to east south of Cerlanted Island to Bagu District.

By the end of May 1941, 46 concrete shelters on the Harparskog line were ready for operation and 141 trenches were under construction. There were also 46 ready cannons, 13 cannons under construction and 113 machine gun positions under construction. A total of 57.8 km of barbed wire barriers and 3.8 km of tank barriers were built in this line.

The structures of the Harparskog line are largely preserved. The monument to the line is located at the place where Carl Gustav Emil Mannerheim crossed on 15 December 1941. The name of this line is taken from the village it passes through.
