The history of Suomenlinna
From Swedish Bastion to Finnish Icon
Suomenlinna, originally named Sveaborg (Fortress of Sweden), began construction in 1748 on a group of islands off Helsinki. Swedish Admiral Augustin Ehrensvärd designed it as a maritime fortress and naval base to defend the Kingdom of Sweden against the Russian Empire in the Baltic Sea. Ehrensvärd adapted 17th and 18th-century European fortification principles, specifically the bastion system, to the rocky terrain of the archipelago. The project involved thousands of soldiers, prisoners, and craftsmen over several decades.
A Shifting Allegiance and Enduring Legacy
In 1808, during the Finnish War, Sveaborg surrendered to Russian forces after a siege. Commandant C.O. Cronstedt's decision remains a historical mystery. This surrender led to Russia's annexation of Finland in 1809, and the fortress became a Russian naval base. Under Russian rule, the fortress was expanded with new barracks. During the Crimean War in 1855, Sveaborg sustained damage from an Anglo-French bombardment but remained under Russian control. Following Finland's independence in 1917, the newly formed Finnish government took over the fortress in 1918 and renamed it Suomenlinna, meaning 'Castle of Finland'. Its military role decreased after World War II, and in 1973, it was converted for civilian use, becoming a UNESCO World Heritage Site in 1991. Today, Suomenlinna is a residential district of Helsinki with around 850 inhabitants.
What to see in Suomenlinna
- Augustin Ehrensvärd's Tomb — Located in the Great Courtyard, this is the resting place of the fortress's founder. The tomb was designed in collaboration between King Gustav III, artist Johan Tobias Sergel, and Carl August Ehrensvärd.
- The Great Courtyard (Suuri Linnanpiha) — This was the central square and administrative area of the fortress. Its architectural design, a work of Augustin Ehrensvärd and Carl Hårleman, uses false perspective.
- Suomenlinna Church — Originally an Orthodox garrison church built in 1854 for Russian troops, it was converted to a Lutheran church in 1918. Since 1929, its central dome has served as a lighthouse, flashing the Morse code letter 'H' for Helsinki.
- The Dry Dock (Kuivatelakka) — This is one of the oldest operating dry docks in the world. Construction began in the 1750s to build Sweden's archipelago fleet. Today, it is used for repairing traditional ships.
- The King's Gate (Kuninkaanportti) — This ceremonial entrance to the fortress, built between 1753 and 1754, is a symbol of Suomenlinna. It features defensive characteristics like gun holes and fortified walls, and wide steps leading to a drawbridge.
- Kustaanmiekka Fortifications — These ramparts and bastions offer views of the sea and are part of the extensive defensive structures of the fortress. Visitors can explore tunnels and casemates built into the fortifications.
