This area, located minutes away from the city of Mariehamn, is one of the areas that should not be missed, as it narrates the city's maritime history in a practical way. The area is open and includes a high lighthouse and a pyramidal dome that was used by locals to guide sailors to land and a port dedicated to fishing tools and nets. You can also climb to the top of the lighthouse and get majestic views of the ocean and the neighboring islands.
