The most beautiful military monuments Finland

35 min boat trip to Svartholma sea fortress. This fortress was built in 1748 by the Swedes to protect themselves against the Russian invasion. Suomenlinna's big sister, so to speak. Destroyed by the British during the Crimean War, it has since been rebuilt. On the small island, you will find a small museum (free entrance) to understand the history of this fort which was built between Russian and Swedish laws. Also on the spot, there is a small bistro to have a drink or a bite to eat.
