Turku Castle visitor guide — everything you need to know before visiting
Turku Castle (Finnish: Turun linna, Swedish: Åbo slott) stands at the mouth of the Aura river in Turku, on Finland's south-west coast. Building work began around 1280, when Finland was part of the Kingdom of Sweden, making it the oldest and largest surviving medieval building in the country. The castle grew from a modest bailey fort into a formidable royal keep over the 14th and 15th centuries, then was rebuilt again in the 16th century under Gustav Vasa and his sons into a Renaissance royal residence. Today it runs as the Turku Castle Museum — Finland's most-visited museum, with around 200,000 visitors a year — spanning the medieval keep, the Renaissance bailey, the Sture Church and Nun's Chapel, and a series of exhibition rooms in the attic.

From border fort to royal Renaissance court
Turku Castle's seven centuries span a bailey fort begun around 1280, a formidable medieval keep built up through the 14th and 15th centuries, and a full Renaissance rebuild of the bailey under Gustav Vasa and his sons in the 16th century.
The medieval keep and the Renaissance bailey
Turku Castle is really two castles in one: the older, sterner medieval keep (päälinna) with its thick granite walls and narrow stairways, and the later Renaissance bailey (esilinna), rebuilt for the Vasa court with grand halls and a state room.
The attic exhibitions and the underground passages
Beyond the state rooms, Turku Castle's attic holds a series of exhibitions on the history of Turku and the castle itself, while the keep's prisons and underground passages give a darker view of centuries spent as a fortress, armoury and prison.
Getting to Turku Castle
Turku Castle sits about 3 km from Turku's Market Square, an easy walk along the Aura riverbank or a short ride on city buses that stop nearby, and it's close to both the railway station and the Silja and Viking ferry terminals.
On the day — what to know
Wear comfortable shoes for the keep's stone stairways and mind your head on the low medieval doorways; the castle is closed on Mondays and runs shorter hours outside the June–August summer season.
Combining Turku Castle with the rest of the city
Turku Castle sits at one end of the Aura riverbank, making it easy to combine with Turku Cathedral, the museum ships and the Forum Marinum maritime museum along the same walking route into the city centre.
Frequently asked questions
What is Turku Castle?
Turku Castle (Turun linna) is a medieval castle at the mouth of the Aura river in Turku, Finland, begun around 1280 when Finland was part of the Kingdom of Sweden. It is Finland's largest surviving medieval building, combining an older defensive keep with a Renaissance bailey added under Gustav Vasa and his sons in the 16th century. It now runs as the Turku Castle Museum, Finland's most-visited museum.
How do I get to Turku Castle?
The easiest route is on foot along the Aura riverbank from Turku's Market Square, about 3 km and roughly 40 minutes. City buses including lines 1 and 42 run more directly from the centre, and the castle is also within easy reach of the railway station and the Silja and Viking ferry terminals.
Do I need to book a specific time slot?
No. Entry is date-specific rather than timed, so your ticket is valid any time during opening hours on the date you choose. Simply arrive within the published opening hours on your selected day.
What can you see inside Turku Castle?
The medieval keep holds the Sture Church, the Nun's Chapel and its collection of medieval wooden statues, plus prisons and underground passages. The Renaissance bailey holds the King's and Queen's Halls and the King's State Room, and the attic houses exhibitions on the history of Turku and the castle, all covered by the same ticket.
Is Turku Castle Finland's oldest castle?
It is generally considered Finland's oldest and largest intact medieval building, with construction beginning around 1280. Other Finnish castles exist, but none combine the same scale, age and level of preservation.
How long does a visit to Turku Castle take?
Most visitors spend two to three hours exploring the keep, the bailey, the Sture Church and the exhibition rooms. Because entry is date-specific rather than timed, you can move through the site at your own pace.
Is Turku Castle suitable for children?
Yes — the mix of towers, stairways, an armoury and dungeon-like passages tends to capture children's imaginations well. The keep's stone stairs are narrow, so keep younger children close and expect an active visit.
Is Turku Castle accessible for visitors with limited mobility?
Partially. The Renaissance bailey and ground-floor areas are generally accessible, but the medieval keep has narrow stone stairways, uneven floors and low doorways that are not step-free. Contacting the museum ahead of your visit to plan a suitable route is worthwhile.
