You step out onto Market Square and the Baltic wind redirects your plans with a briny, insistent tug — the ferry already cutting a bright wake toward Suomenlinna. The city unfolds in disciplined blocks: neoclassical domes, tram tracks, and the constant business of coffee and commuters, then the sea dares you to cross and meet the fortress islands.
