Kyminlinna Fortress, located on Hovinsaari island in Kotka, Finland, is a significant historic military structure built by Russia after the Russo-Swedish War of 1788–1790. Designed as part of a dual fortification system alongside the Ruotsinsalmi sea fortress, Kyminlinna was intended to defend against land-based attacks along the King's Road. The fortress features a distinctive five-cornered caponier layout spanning approximately 800 meters in diameter and covering around 74 hectares. Its ramparts are intersected by modern infrastructure such as the Kotka railway and national roads. The fortress includes 23 buildings, many now in varying states of disrepair after Finnish Defence Forces ceased using it in 2005. Though it never saw action during the Crimean War, Kyminlinna played a role during the Finnish Civil War, witnessing a battle in 1918. Later, it served multiple purposes including a refugee camp, prisoner of war camp, and hospital during World War II. Today, Kyminlinna stands as an important cultural and historical site reflecting Finland's complex military past and Russian influence in the region.

History

1791

The original fortification at Kyminlinna was a smaller bastion fortress built between 1791 and 1795 under the supervision of Russian Marshal Alexander Suvorov and later General Jan Pieter van Suchtelen.

1803

This initial fortress was demolished to make way for the larger Kyminlinna built from 1803 to 1808, designed by General Suchtelen.

Although incomplete by the Finnish War, the fortress lost much of its military relevance after the Russo-Swedish border shifted north.

1918

Kyminlinna did not engage in combat during the Crimean War but was active during the Finnish Civil War in 1918.

2005

It continued to serve various military and civilian functions through World War II and was used by the Finnish Defence Forces until 2005.
