Suomenlinna

Built on five interconnected islands by the Swedes in 1748 to protect Helsinki from seaborne attack, the fortress of Suomenlinna, fifteen minutes away by boat, is the biggest sea fortress in the world. Reachable by ferry from the harbour, it’s also a great place to walk around on a summer afternoon, with superb views back across the water towards the capital: you can either visit independently or take one of the hour-long summer guided walking tours, beginning close to the ferry stage and conducted in English. Suomenlinna has a few museums, none particularly riveting, but the best of the lot is Suomenlinna Museum, which contains a permanent exhibition on the island.
