Fortress Suomenlinna or Sveaborg is perfectly visible from the board of the ferry "Viking line" when approaching Helsinki. So get your camera ready and fix on the port side of the ship to capture the picturesque views of the fortress, located on several islands. If what you see interests you, then upon arrival at the port of Katajanokka, at the Kauppatori market square, where souvenirs, fish and strawberries are sold, you can take a ticket for a ferry that delivers tourists straight to the fortress.→
