When to go to Helsinki?
Helsinki's Market Square smells of fried herring and summer berries, and the ferry to Suomenlinna leaves from the same quay for an island fortress of grass ramparts, tunnels and shoreline paths. Above the square, the Lutheran cathedral stacks its white steps and green domes. Inland, Temppeliaukio was cut into bare rock, its copper ceiling floating over walls left raw.
