Suomenlinna (dal 1748): la grande fortezza marittima sulle isole di Helsinki
Costruita dagli svedesi a metà Settecento su un gruppo di isole davanti a Helsinki, Suomenlinna doveva sbarrare il Baltico alla Russia. Cambiò bandiera più volte — svedese, russa, finlandese — e resta uno dei più grandi esempi di architettura militare marittima d’Europa, oggi quartiere abitato di Helsinki.
At a glance
Suomenlinna (“the fortress of Finland”) is one of the great sea fortresses of the world, built from 1748 by Sweden on a chain of islands guarding the approach to Helsinki. Designed against the rising power of Russia, it changed hands as the region’s history turned: Swedish, then Russian after 1808, then Finnish from 1918. Its bastions, walls, dry dock and barracks, adapted over two centuries, make it an exceptional monument of military architecture. It was inscribed by UNESCO in 1991.

History
In the 18th century Sweden, alarmed by Russian expansion, began in 1748 a massive fortress on the islands off Helsinki, then a Swedish town. Augustin Ehrensvärd directed the work, raising bastions, a naval dockyard and quarters for thousands of soldiers, a project so costly it shaped the whole region. The fortress was named Sveaborg, “the fortress of the Swedes”.
In 1808 it surrendered to Russia, which held it for over a century and added its own buildings; the Crimean War brought a British-French bombardment. When Finland gained independence in 1917–18 the fortress became Finnish and was renamed Suomenlinna. Demilitarised in the 20th century, it became a residential district and museum island.
What you see
Ferries cross from Helsinki to the islands, where paths lead among grass-topped bastions, tunnels and gun emplacements looking out to sea. The King’s Gate, the great dry dock (still in use), barracks in brick and timber, and Ehrensvärd’s tomb tell the fortress’s story across two centuries.
Museums, cafés and the homes of residents share the islands, which double as a popular Helsinki retreat.
