Valsörarna (in Swedish) or Valassaaret (in Finnish) is a small archipelago in Korsholm, Finland, located in the Kvarken region of the Gulf of Bothnia. The islands are the last you see when going by boat or ferry from Vaasa, Finland to Umeå, Sweden. The archipelago is detached from Korsholm's main Replot-Björkö archipelago. They are uninhabited and there is no road access. However, they are an important bird sanctuary, frequented by birdwatchers and ornithologists. They are included in the UNESCO World Heritage List along with the High Coast of Sweden and the archipelago of Kvarken, for exhibiting the effects of land rise due to post-glacial rebound. History The name The name Valsörarna is of Swedish origin. It is believed that the name was derived from the stone-clad shores and the moraine which resembles a whale. The Finnish name Valassaaret is believed to have been derived from the Swedish word. An old route between Finland and Sweden The Valsörarna is the shortest route to the Swedish island Holmsö only away. During winter, the waters of Kvarken are completely iced and it was possible to walk over to the neighbouring country that way. Today, this is not possible because of active ferry traffic and lanes that are kept open by icebreakers for commercial shipping. This fact was used during the Finnish War by Russian general Barclay de Tolly who used this route in November 1809 when marching over to Umeå. The march to Sweden with about 3700 soldiers was successful but failed on the return trip. The severe cold of the spring and the lack of food took their toll on the men and it is estimated that 400 died from the cold alone. The remains of these soldiers were still present around Valsörarna in the 1900s. In memory of the fallen men, there is now a memorial mound of stones raised on Äbbskär. A saying tells the tale that the inhabitants of Valsörarna grew tired upon always finding skeletons everywhere around the islands and collected them all in one place, which today is the mound of stones. The lighthouse is built There was a sailmark made out of a tree on the island in the 1850s, but that became inefficient for use in the dangerous waters of Kvarken as traffic increased. The long thought-of lighthouse became reality after five boats ran aground on the same night in 1879. The lighthouse was designed
