The Suomenlinna Church

The Suomenlinna Church was built as a Russian Orthodox garrison church in 1854. The original building had five steeples with onion domes. The appearance of the church – which dominates the southern horizon from Helsinki – was changed at the beginning of the Finnish era in the 1920s when it was converted into an Evangelical-Lutheran church.

The bases of the small domes were left under the roof. The kokoshniki and other ornamental elements of the Russian Orthodox church were removed from the walls, which were then plastered to form an even surface.

The church steeple doubles as a lighthouse for air and sea traffic. The signal blink of the lighthouse is the Morse code for the letter “H” for Helsinki.

Other services

Various events and concerts are organised in the hall every year. At Christmas time, a charming nativity crib is on display.  fortress’s ceramic crib was made by an artist from Suomenlinna.

The crypt of the church can be rented for small events. Food and drinks can be ordered for the events. The crypt seats approximately 60 people. Those arranging events at the crypt should bear in mind that serving alcohol is restricted to one glass per person.

How to get there

The Helsinki City Transport ferry operates to the main pier throughout the year, and from there the church is about 200 metres away. The waterbus stops at the Visitor Centre pier during summer, and the church is about 300 metres from there.


The route from the main pier to the church is accessible with wheelchair. The road at the main entrance, however, is steep (inclination 14%) and there are some steps on the route. Access to the churchyard and the main entrance is more gently sloped from the Parade Field side.

There is a staircase at the entrance. Detachable trough-shaped ramps can be erected by the caretaker upon request. However, the ramps are rather steep and designed mainly for prams and pushchairs. There are some steps on the route from the main entrance to the church hall.  Steps lead to the altar. There are no places specified for wheelchair users in the church hall; the only space is in the aisle or in front of the first row of seats.

The parish hall and a children’s playroom are located on the cellar level. The nearest accessible toilet is located in the Suomenlinna kiosk in the Jetty Barracks.
