Söderarm lighthouse, Maritime lighthouse on Torskär island, Sweden
Söderarm is a cylindrical granite lighthouse standing on an island in the Stockholm archipelago near the western Sea of Åland. The tower rises 21 meters and sits on rocky terrain surrounded by water and smaller islands.
The lighthouse was built in 1839 and initially used colza oil with mirrors to produce light. In 1882 kerosene lamps replaced the original system as technology advanced.
The lighthouse embodies the maritime heritage of the region and represents the connection between Sweden and its archipelago. Today visitors experience the site as a window into traditional seafaring life and the relationship people built with these remote waters.
Visitors can stay overnight in the former keeper's house while exploring the surrounding islands. The remote island location requires water access and makes wildlife observation including seals and sea eagles a natural part of the experience.
The lighthouse was automated in 1997, ending 158 years of continuous human presence on the island. This transition marked a turning point in how Sweden managed its remote lighthouse stations and led to their preservation as cultural heritage.
