Welcome to Suomenlinna to walk the Lighthouse Keeper’s Route from 28 November 2025 to 29 January 2026!
On this self-guided route, you’ll navigate with a map to windows twinkling in the dark. Discover Svante and his friends, each with their own story of life in the fortress. Wander at your own pace, alone or with a companion. A touch of lighthouse light shines in the lanterns of Svante and his friends. Find two, three, or even all eight lantern bearers!
You can get a paper map from the Suomenlinna Visitor Centre during its opening hours (Rantakasarmi, C1 Suomenlinna, opposite the main pier) or digitally from the Suomenlinna digital guide by scanning the first point from the window of Rantakasarmi.
