The pink-plastered Jetty Barracks, built during the Russian era, is the main gateway to the fortress. The building dominates the northern shoreline of Suomenlinna. It is the first building visitors see as they arrive at the main quay.
The vaulted, tin-roofed stone barracks was built in 1868–70. It was designed to accommodate 250 soldiers in peacetime.
One part of the building was used as the main guard house with detention rooms, rooms for prisoners as well as rooms for the guards and the officer on duty. In addition, the barracks included a kitchen, the men’s living quarters and lavatories.
The main quay is located immediately in front of the Jetty Barracks. During the summer season, waterbuses operate to the Artillery Bay quay which is approximately 500 metres away from the Jetty Barracks.
