★★★★★ Museum & culture
No admission charge for anyone. Parking or transport may still cost.
VERIFIED FREE. A UNESCO-listed 18th-century sea fortress across six islands, and a residential neighbourhood of 800 people. The fortress costs nothing - you pay only the HSL ferry, EUR 3.30 on a standard AB ticket, which is the same ticket as the tram. Ferries run year-round and cut through the ice in winter. Museums inside charge separately.
