Overview

The Vesikko is a historic Finnish submarine currently preserved as a museum ship on the island of Suomenlinna in Helsinki. Originally commissioned as a prototype, the submarine was built in Turku and launched in 1933. It served the Finnish Navy during the Second World War, specifically during the Winter War and the Continuation War, patrolling the Baltic Sea. Unlike many of its contemporaries, the Vesikko was not scrapped following the 1947 Paris Peace Treaty, which prohibited Finland from possessing submarines. Instead, it was preserved and eventually opened to the public as a museum vessel. Visitors to the site can explore the cramped, authentic interior of the submarine, gaining a firsthand understanding of the technical challenges and daily life experienced by the crew during wartime operations. As one of the most unique local attractions in the Helsinki maritime area, the site offers a rare glimpse into naval engineering history. When planning your trip ideas for exploring the Suomenlinna fortress, the Vesikko stands out as a primary point of interest. The museum is best experienced in the morning or early afternoon to avoid crowds, and because the vessel is located outdoors on the island, it is advisable to check the local weather forecast before visiting to ensure a comfortable walk through the historic naval site.

Did you know

  • The Vesikko was designed by the Dutch engineering firm Ingenieurskantoor voor Scheepsbouw, a front for the German Navy to circumvent the Treaty of Versailles.
  • The submarine's name, 'Vesikko', refers to the European mink, a species native to the region.
  • It is one of the very few surviving submarines from the Second World War era globally.

History

Designed in the early 1930s, the Vesikko (originally designated CV-707) was a technological precursor to the German Type II U-boats. After its construction in Finland, it was commissioned into the Finnish Navy in 1936. During the Continuation War (1941–1944), the Vesikko conducted several patrol missions in the Baltic Sea, notably sinking the Soviet merchant vessel Vyborg in July 1941. Following the conclusion of hostilities and the subsequent Paris Peace Treaty in 1947, the Finnish military was strictly forbidden from operating submarine vessels. While the rest of the Finnish submarine fleet was dismantled and sold for scrap, the Vesikko was spared due to its historical value and eventual transition into a museum piece, officially opening to the public in 1973.

Cultural significance

The Vesikko serves as a vital artifact of Finnish naval heritage and a somber reminder of the maritime conflicts in the Baltic Sea during the Second World War. It represents a period of intense military innovation and the complex geopolitical landscape of 20th-century Northern Europe. By maintaining the vessel in its near-original state, the museum provides an educational environment that honors the service of the Finnish submariners. It remains a key cultural landmark within the Suomenlinna UNESCO World Heritage site, highlighting the island's long-standing role as a defensive bastion for Helsinki and the broader Finnish state.

Geography and landscape

The Vesikko is situated on the island of Susisaari, one of the islands comprising the Suomenlinna sea fortress, located just off the coast of Helsinki. The submarine rests in a dry dock, surrounded by the rugged, rocky terrain and historic stone fortifications that characterize the island. The area is defined by the harsh Baltic climate, with the vessel exposed to the winds and sea air. The surrounding landscape features a mix of military architecture, grassy slopes, and panoramic views of the Gulf of Finland, creating a distinct atmosphere that contrasts the claustrophobic interior of the submarine with the expansive maritime horizon.
