The Great Wall of China, the Acropolis in Athens, the Grand Canyon, and Suomenlinna. UNESCO’s World Heritage List brings Suomenlinna together with a long list of cultural and natural sites that are considered common property of all of humanity. Welcome to Suomenlinna!
Reinforcing the defences of Finland, then a part of Sweden, was deemed necessary. In 1747, the Swedish parliament made a decision to build a central fortress including a naval base in Helsinki. Fortification work begun the following year.
In 1991, the Suomenlinna fortress was added to the UNESCO World Heritage List as a unique monument of military architecture. Another special feature of the fortress is that in the course of its history it has served in the defence of three realms: Sweden, Russia and Finland.
