Finnish lighthouses are essential navigational aids located along the country's extensive coastline and numerous islands. They help guide ships safely through the often treacherous waters of the Gulf of Finland and the Baltic Sea. Many of these lighthouses are historic structures, showcasing unique architectural styles and designs that reflect Finland's maritime heritage. There are over 50 operational lighthouses in Finland, with some dating back to the 18th century. Notable examples include the Hanko Lighthouse, known for its striking red and white stripes, and the Kylmäpihlaja Lighthouse, which offers accommodations for visitors. These lighthouses not only serve a practical purpose but also attract tourists interested in Finland's coastal beauty.
