#1 of 1,730 in Things to do in Finland
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.
