Vesikko

Vesikko is a submarine preserved as a museum ship on Suomenlinna fortress island, where visitors can explore its interior structure and engineering. The vessel is equipped with diesel and electric motors and contains narrow passages connecting multiple deck levels throughout its length.

Built in the 1930s, this submarine served in the Gulf of Finland during World War II before being preserved after international agreements restricted Finland's naval capabilities. It became the sole surviving Finnish submarine, making it an irreplaceable record of the nation's wartime naval operations.

The vessel represents how Finland maintained its naval capabilities during difficult times and remains a symbol of the nation's maritime past. Walking through its compartments gives a sense of how the crew lived and worked in these confined spaces.

The museum is located on an island and reached on foot, though exploring the confined interior requires some physical comfort with tight spaces and low ceilings. Visitors should be prepared for steep stairs and limited headroom in certain compartments.

The submarine was originally commissioned by a Dutch engineering firm, not built directly for Finland, giving it an unexpected international origin. This unusual background reveals how countries shared naval technology and expertise across borders during that era.
