About Turku

Turku claims the title of Finland's oldest city, its riverfront dominated by the red-brick Turku Castle, one of the North's greatest medieval fortifications. The Aura River flows through the center like a veining of life, its banks lined with wooden warehouses now converted to galleries, restaurants, and cafés. This university town pulses with youthful energy while maintaining dignified historical layers—Gothic cathedral, 18th-century quarters, modernist additions all stacked like proof of centuries.

Turku is Finland's oldest city and former capital, with a medieval castle guarding its river mouth and a cathedral at the heart of its old town. Its real charm, though, is the riverside — restaurant boats line the Aura River, and the surrounding archipelago of thousands of islands makes it one of the best gateways to Finland's coastal scenery.

Traveler reviews

★★★★☆

Spent an afternoon on the restaurant boats along the river, which was a really relaxed way to see the city. The castle was more interesting than we expected.

★★★★★

Took a ferry out into the archipelago for a day and it completely changed our impression of the area — so many small islands to explore.

Easy day trip from Helsinki by train, though we wished we'd stayed overnight to enjoy the riverside in the evening.
