Suomenlinna Fortress Walking Tour

Originally an Eastern Orthodox Russian garrison church (1854), converted to Lutheran in 1918 after Finnish independence. The church tower doubles as a lighthouse — one of only a few in the world.

Built in 1753–54, this was the ceremonial entrance for visiting dignitaries arriving by sea. Named after King Adolf Frederick of Sweden. The stone dolphins flanking the gate are the fortress's most photographed feature.

Launched in 1933, Vesikko is Finland's only surviving WWII submarine. It served in the Winter War (1939–40) and Continuation War (1941–44). The 1930 Helsinki Naval Treaty restricted submarines — Vesikko was nearly scrapped but preserved as a museum ship in 1959.

The building dates to the 1880s Russian period, when Suomenlinna served as a naval base for the Imperial Russian Navy. The museum covers Finnish military history from the Swedish era through independence, with a strong focus on the fortress's 250+ years of active service.

Constructed in the 1750s under Swedish rule, the dry dock could service naval vessels up to frigate size. It was vital for maintaining the Swedish archipelago fleet during the era when Russia and Sweden were locked in a century-long struggle for Baltic supremacy. Still used today for wooden ship restoration.

The heart of the fortress's military life. During the Swedish era (1748–1808), this is where troops drilled and supplies were distributed. After the Russians took the fortress without a fight in 1808 (during the Finnish War), it became the administrative center of the Russian Baltic Fleet's base at Sveaborg.

Named after Swedish fortress architect Augustin Ehrensvärd's deputy, Zander. This bastion was part of the "ring fort" design — a star-shaped defensive system with overlapping fields of fire. The fortress was designed by Ehrensvärd in 1747 on the orders of King Frederick I of Sweden to counter Russian expansion.

Built in the late 19th century during the Russian period to house the expanded garrison. After Finnish independence in 1917, the barracks served the Finnish coastal artillery until the 1970s, when the fortress transitioned to civilian use. The brewery here produces the island's own ale, referencing the garrison's historical beer rations.

The huvudbrygga was the principal landing point for the fortress throughout its military history — first for Swedish supply vessels, then Russian naval traffic, and later Finnish coastal administration. Unlike the modern HSL commuter pier (päälaituri) on the south side, this pier is the historic arrival point and sits close to the church and visitor center.
