One of the world’s largest maritime fortresses

Suomenlinna is a maritime fortress that was built off the coast of Helsinki in 1748. Here you can get a real feel for Finland’s position between East and West; Suomenlinna was shaped by three distinct historic eras when helped defend first Sweden, then Russia and ultimately Finland.

Suomenlinna is a UNESCO World Heritage Site as a notable example of European military architecture. Suomenlinna is among the most popular sights in Finland and a living district that is home to 850 city residents. With its museums and events, and its cosy cafes and restaurants Suomenlinna offers a unique experience for visitors of all ages. Especially children can have a great time exploring the many tunnels of the old fortress.

It is good to reserve at least half a day for a visit to Suomenlinna. The vast fortress is best explored on foot, so prepare for some hiking with good shoes and a windbreaker. During the summer (from 1 June to 31 August) guided walking tours are arranged daily in English at 11am, 12:30pm and 2:30pm. 

Suomenlinna is open year-round and you can get there with the municipal (HSL) ferry that departs from the Market Square throughout the year. In summertime you can also take a JT-Line waterbus from the Market Square. The journey takes around fifteen minutes.

Recreational islands Lonna and Vallisaari

The island Lonna has an interesting history. In the 1880s it was used by the Russian Navy to store mines, in the 1920s it was used as a base for clearing mines, and in the post-war period ships were demagnetised there. Now the island is open to the public featuring a café and restaurant. You can get to Lonna in summertime aboard the JT-Line waterbus to Suomenlinna with departures approximately once every hour. The waterbus departs from the Market Square and stops at Lonna on the way to Suomenlinna.

The island of Vallisaari between Santahamina and Suomenlinna opens up to the public in May 2016. Formerly used by the Finnish Defence Forces, the island offers visitors the chance to enjoy its diverse flora and spectacular views, as well as its well preserved historic fortifications. In its first year Vallisaari can be explored along marked trails, and guided tours will also be available. A ferry connection from the Market Square will begin operating on 14 May 2016.

Seurasaari is the only open-air museum in Helsinki
