Mannerheim Line

The Mannerheim Line was a defensive fortification built by Finland along its southeastern border with the Soviet Union before World War II. Named after Finnish military leader Carl Gustav Emil Mannerheim, it consisted of bunkers, trenches, and other military installations designed to protect against a potential Soviet invasion. The line gained prominence during the Winter War (1939-1940) when the Soviets attacked Finland. Despite being heavily outnumbered, Finnish forces put up a determined defense, highlighting the strategic importance of the Mannerheim Line in Finnish history as a symbol of national resilience.
