Suomenlinna is a maritime fortress located very close to Helsinki. It is a UNESCO World Heritage Site and one of Finland’s most popular tourist attractions. Suomenlinna is also one of the districts of the City of Helsinki and home to 800 year-round residents.
The history of the Suomenlinna fortress is closely tied to the history of Finland and the Baltic Sea. The fortress was built in the mid-18th century to serve as a cornerstone of the eastern defences of the Kingdom of Sweden, to which Finland then belonged. The fortress was taken by Russia at the beginning of the 19th century. Under Russian rule it guarded the shipping lanes leading to St Petersburg together with naval bases in Tallinn and Kronstadt. In 1917, Finland became independent and took over the maritime fortress the following year. Suomenlinna offers something to see and experience for visitors of all ages: rich and varied nature, fortifications, artillery, tunnels, museums and many cafés and restaurants.
The waterbus service by JT-Line operates between the Kolera Basin stop by the Market Square and Artillery Bay and King’s Gate in Suomenlinna from 1 June to 27 September 2020.
Vallisaari & Kuninkaansaari
Vallisaari island and the neighbouring Kuninkaansaari island have been open to the public since May 2016, after having been released from military use. The islands are managed by Metsähallitus, which is responsible for developing operations on the islands while also protecting their natural and cultural values. The islands are situated right next to Suomenlinna. Only the narrow Kustaanmiekka sound separates Vallisaari from Suomenlinna, whereas Kuninkaansaari and Vallisaari are connected by a narrow causeway.
Nature meets history in a unique way on Vallisaari and Kuninkaansaari. In proportion to their surface area, the islands possess the richest biodiversity in Helsinki. What is more, the famous Alexander battery, casemate batteries and garrison buildings that were built during the period of Russian rule all have interesting stories to tell about the history of the area.
The waterbus service by JT-Line operates between Helsinki Market Square and Vallisaari from 1 June to 27 September 2020.

Lonna is a small island situated between the Market Square and Suomenlinna that was opened to the public in summer 2014. The island has been the site of a sea mine depot and later a demagnetisation base, among other things. The demagnetisation base was in use from the Continuation War right up to the 1960s, as there were a lot of sea mines in Finnish territorial waters which were set off by the magnetic fields in ships’ hulls. The demagnetisation station’s equipment reduced these magnetic fields. Today Lonna has a cosy restaurant and café. The old demagnetisation equipment is on display for visitors in an exhibition area in the restaurant.
