The Svartholm is located near the Gulf of Loviisa. It is a sister fortress of Suomenlinna and belongs to the same defense chain. Construction work on the island began in 1748 on the basis of plans by Augustin Ehrensvärd. The work was mainly completed during the 1750s.

The Swedish fortification period in Svartholm ended in 1808, when Svartholma surrendered to the Russians almost without resistance. During the Crimean War in 1855, the English naval department blew up the island’s equipment and rendered the fort dilapidated. Since the 1960s, the fortress has been restored under the direction of the National Board of Antiquities.

Svartholm is a popular place for the whole family to visit. You can travel there by FRS Finland’s vessel or by own boat. Guided walking tours are available on the island. Free guest berths are available for boaters. There is also a summer restaurant on the island.
