Suomenlinna, until 1918 Viapori (Finnish), or Sveaborg (Swedish), is an inhabited sea fortress built on six islands (Kustaanmiekka, Susisaari, Iso-Mustasaari, Pikku-Mustasaari, Länsi-Mustasaari and Långören), and which now forms part of the city of Helsinki Wikipedia Icon, the capital of Finland.

Suomenlinna is a UNESCO World Heritage site and popular with both tourists and locals, who enjoy it as a picturesque picnic site. Originally named Sveaborg (Fortress of Svea Wikipedia Icon), or Viapori as called by Finns, it was renamed Suomenlinna (Castle of Finland) in 1918 for patriotic and nationalistic reasons, though it is still also sometimes known by its original name. In Swedish-speaking contexts, the name Sveaborg is always used.

The Swedish crown commenced the construction of the fortress in 1748 as protection against Russian expansionism. The general responsibility for the fortification work was given to Augustin Ehrensvärd Wikipedia Icon. The original plan of the bastion fortress Wikipedia Icon was strongly influenced by the ideas of Vauban Wikipedia Icon, the foremost military engineer of the time, and the principles of Star Fort Wikipedia Icon style of fortification, albeit adapted to a group of rocky islands.

In addition to the island fortress itself, seafacing fortifications on the mainland would ensure that an enemy would not acquire a beach-head from which to stage attacks. The plan was also to stock munitions for the whole Finnish contingent of the Swedish Army and Royal Swedish Navy there. In the Finnish War the fortress surrendered to Russia on May 3, 1808, paving the way for the occupation of Finland by Russian forces in 1809.
