Visit World Heritage Site Sea Fortress Suomenlinna to see a sea fortress built on a collection of six islands. This ruggedly beautiful spot is a favorite among both locals and tourists. The fortress was built in 1748 and inhabited by Swedes and Russians until 1918, when it became a part of independent Finland. View the impressive fortified structure, constructed by the Swedish crown to withstand attacks from 18th-century Russia (who eventually overtook the islands in 1808). Nowadays the site supports a town with civilian inhabitants and draws visitors from the mainland of Finland.

  • Free to visit via the ferry if you have a travel pass for the transportation in Helsinki. I visited for a couple hours and walked around. There was a lot more to see, and I will probably be back to visit more when there is warmer weather. It is very quiet and peaceful and there is a lot of history to uncover by visiting there.
  • this was a very cool place to go, and there is a grocery store if you need anything. Lots of cave type passageways and just a very interesting place to walk around.
