The Suomenlinna open-air theatre

The open-air theatre is located on Susisaari island, in the Hyvä Omatunto (‘Good Conscience’) ravelin. The theatre has operated in the ravelin since 1968. Plays such as The Seagull, Max & Moritz, The Brother Lionheart, The Lord of the Rings and The Unknown Soldier have been staged at the theatre. Summer Theatre

RyhmäteatteriThe Ryhmäteatteri and Q-teatteri theatre groups are responsible for the plays in alternate years.

The ravelin of Good Conscience and the bastions Virtue and Honour are all part of the outer bastion ring of Susisaari, making up a system for protecting the fortress against attacks from the southeast.

The theatre seats nearly 500 people. Thanks to a large canopy, the theatre is the fortress’s largest ‘indoor’ space.

Canopy prolongs the theatre season

Summer TheatreBefore 1993, the theatre had no canopy, with the exception of the temporary shelter built by the Ryhmäteatteri theatre group in 1988 and 1989 for their production of The Lord of the Rings.

The canopy is made from a steel framework arch structure with a light grey material stretched across it. Images can be projected onto the canopy. In addition, the canopied stage enables different solutions for lighting and staging plays as well as live music.

The tent-like canopy shelters the audience as well as the whole inner courtyard of the theatre, which means that the theatre can open from early in the spring and continue its season late into the autumn, for example for concerts.

How to get there

The Helsinki City Transport ferry operates to the main pier throughout the year, and from there the theatre is about 700 metres away. The waterbus stops at the Visitor Centre pier during summer. The theatre is about 200 metres from the pier.


Getting to the open air theatre by wheelchair requires some special arrangements to be made in advance, for instance when purchasing theatre tickets. The theatre personnel will guide wheelchair users to their place in the audience. The route leads through the make-up room and across the stage to the audience via a ramp. The route is mainly on even and accessible terrain. The facilities and settings of the auditorium and the stage vary according to the production in question, but there is room for a couple of wheelchairs at the bottom of the auditorium.
