Suomenlinna is a historic sea fortress and a Unesco world heritage site. The construction of the fortress began in 1748. The purpose of Suomenlinna was to protect the Eastern border and the coast in the wars against Russia. As a result of the Finnish Civil War, the fortress was turned into a prisoner of war camp in 1918. In 1918, the fortress was taken over by the Defense Forces and renamed Suomenlinna.

The fortress is one of the most popular destinations in Finland, with about a million visitors a year. Suomenlinna also has about 800 inhabitants. The island has museums, cafés, restaurants and artisan studios. Suomenlinna hosts various events throughout the year.
