Suomenlinna - the Sea Fortress of Helsinki

The fortress of Suomenlinna is one of Finland’s most popular sights. It is only a very short ferry crossing away from Helsinki.

This base for the archipelago fleet was originally built midway through the 18th century, when Finland was part of the Swedish kingdom. In 1991, Suomenlinna was designated as a UNESCO World Heritage Site.

The different parts of the six islands offer a variety of atmospheres; whether you are looking for a cheerful weekend with friends, a tranquil evening stroll or perhaps a jog – it is all made possible by the diverse routes and locations across the islands. During the summer when the nights are warm, it is possible to stay on Suomenlinna until rather late at night. The last ferry of the day departs from Suomenlinna at two o’clock in the morning.


Helsinki is a modern, pocket-sized European city known for design and high technology. Helsinki’s attractive and unique character comes from its proximity to the sea, as well as its location between the East and the West.
