Ahvenkoski (Swedish: Abborfors) is a historical site in the Kymenlaakso region, Finland, located by the westernmost branch of the river Kymijoki. It consists of the Vähä-Ahvenkoski (Swedish: Lillabborfors) village in Loviisa and the Ahvenkoski village in Pyhtää. The site is especially known of its rich military history. Between 1743 and 1809, Ahvenkoski was a border crossing of Sweden and the Russian Empire. Ahvenkoski was originally part of the Pyhtää municipality. As the border divided the village in two, the Swedish side became known as Ruotsinpyhtää, the Swedish Pyhtää, which was annexed to the town of Loviisa in 2010.[1]
Ahvenkoski is listed as a Cultural environment of national significance by the Finnish National Board of Antiquities. The Ahvenkoski rapid was mostly destroyed in the 1930s, as the water level rose several meters due to the construction of a hydroelectric power station.[2]
