Introduction
Suomenlinna is a sea fortress spread over several islets off Helsinki, begun by Sweden in the 18th century to guard against imperial expansion and later enlarged by Russia — a UNESCO World Heritage site. Massive walls, batteries and tunnels link museums, homes and barracks; a short ferry ride feels like stepping into another era. Summer picnics on the grass and island walks, winter's snow on stone — both a historic site and Helsinki residents' favourite near-island retreat.
