Naval battles in the Ruotsinsalmi straits
In August 1789, the Swedish Navy was ready for battle at the narrowest point of the Ruotsinsalmi straits when Russia invaded. However, the Swedes quickly saw their ammunition diminish alarmingly and the Swedish Navy received the order to retreat.
A chaotic escape began, leading to the first sea battle defeat of Sweden in the face of overwhelming Russian superiority. After the battle, the Swedes feverishly began to reinforce their fleet. The war was not over yet.

For a year the war was fought on land. In the summer of the following year, the Empress Catherine of Russia, who had had enough of Sweden’s aggression, ordered her navy to destroy the Swedish fleet.
The fleets encountered each other once again in the Ruotsinsalmi area. The intense cannon fire started early in the July morning and continued throughout the day, sometimes with the gunpowder smoke completely obscuring the visibility. The weather conditions were not favourable to the Russian fleet as the wind pushed some of their incapacitated ships onto reefs. As night came on, it became so dark that there was nothing visible to shoot at and finally it became very quiet.
As the following morning dawned, the battle damage became evident. The wind had driven the Russians into chaos and many of the ships had fled. Russian ships were seized, sunk, or burned. King Gustav III of Sweden had survived the naval battle of Svenskund as the overwhelming winner.

The consequences of the naval battle can still be seen today
The war of Gustav III caused dissatisfaction among Finnish officers. It is said to have been the impetus for Finland's separation from Sweden to become an autonomous part of Russia.
As a result of the sea battles, the Russians built a sea fortress system consisting of a number of separate forts, redoubts, and artillery batteries in Kotka and the surrounding areas.
During the fighting, dozens of ships sank in the Ruotsinsalmi area, of which several wrecks have been located and investigated. Together with the nature of the area, they form an interesting underwater landscape. Some wrecks, such as the frigate Sankt Nikolai, have been investigated and objects have been brought to the surface. The cannons recovered from the Sankt Nikolai surveys can be found on Varissaari Island along with a war memorial of the Battle of Svenskund.
Why and how is this location protected?
The entire naval battle area, i.e. 26 km2, is a protected ancient remnant area protected by the Antiquities Act (295/1963). This area is delineated on the map based on wreckage finds and old maps of the battle. The delineation is an estimate and will be updated as necessary on the basis of new research data. The Antiquities Act protects the area’s wrecks (and parts thereof) that can be presumed to have sunk at least 100 years ago.
