Ahvenkoski, Historical site and Cultural Heritage Site at Kymi River, Finland.
Ahvenkoski is a historic site spanning two municipalities, Loviisa and Pyhtää, where the Kymi River flows through an area shaped by natural resources and historical structures. The location shows how the river landscape was used and occupied across different time periods.
From 1743 to 1809, this location served as a critical border crossing between Sweden and the Russian Empire, shaping regional development. Control of the crossing reflected broader political shifts that affected the surrounding area.
The site holds Viking Age archaeological remains found in 2010 that reveal how maritime trade shaped life here for centuries. Objects discovered in the soil show connections between communities and the importance of river transport in daily commerce.
This location is accessible by local roads from both municipalities and visitors can explore various historical areas on their own or with guides. The terrain is uneven in places, so comfortable walking shoes are recommended for getting the most out of a visit.
The Battle of Ahvenkoski in April 1918 was the final major clash between German forces and Finnish Red Guards during the Finnish Civil War. This confrontation marked a turning point in the history of the region and the newly independent nation.
