Suomenlinna Fortress in Winter, Helsinki - Unesco World Heritage Site FINLAND

Suomenlinna Fortress is probably the best tourist attraction in Helsinki: a 15 minute ferry ride crossed ice water takes you to the winter wonderland where you can walk around for hours and enjoy all the snow, ice, wind and some hot drinks in the restaurant. Suomenlinna Fortress was added to the UNESCO World Heritage List in 1991 as a unique monument of military architecture.
