Trade-off

UNESCO 18th-century sea-fortress on six islands — 15-minute ferry from the Market Square and 800 residents.

A genuine living island community — 800 Finns live full-time in the old garrison buildings — and a UNESCO heritage site simultaneously. Day-trip-able in 3 hours but staying overnight in one of the few guesthouses (Hostel Suomenlinna) lets you have the ramparts to yourself after the last ferry. Cars are banned.
