Hanko: Two lighthouses in front of Hanko, the southernmost city of Finland. The white lighthouse tower stands on Gustavsvärn, an island with ruins of fortifications built by the Swedes in the late 18th century. The other lighthouse is situated on Russarö, an island occupied by the Finnish Defence Forces. I visited Gustavsvärn on July 5th, 2005.
