Suomenlinna Sea Fortress

A Unesco World Heritage Site, Suomenlinna sea fortress is one of the most popular attractions in Finland for a reason. Suomenlinna was shaped by three historic eras when it helped to defend first Sweden, then Russia and ultimately Finland. With its museums, events and restaurants Suomenlinna offers a unique experience for visitors of all ages. The fortress is easily accessed all year by public transport ferry from the Market Square. In summer also by JT-Line ferry. In summer guided walking tours are organized daily in Finnish, Swedish, English and Russian, occasionally also Chinese. During the winter season, tours are available on weekends in English, in spring also in Russian. The tours start from the Suomenlinna Centre and last approx. one hour. Tickets can be bought at the Suomenlinna Centre or online.
