Turku Castle 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 in stages over three centuries: a modest bailey fort became a formidable royal keep, then — under Gustav Vasa and his sons in the 16th century — was rebuilt again into a Renaissance residence with grand halls fit for a royal court.
The castle's two parts tell two different stories. The medieval keep (päälinna) holds the older, sterner architecture — thick granite walls up to five metres deep at the base, narrow stairways, and the atmospheric Sture Church and Nun's Chapel, home to a collection of medieval wooden religious statues found nowhere else in Finland. The Renaissance bailey (esilinna), added later, holds the King's and Queen's Halls and the King's State Room, decorated for the Vasa dynasty's court life rather than for defence.
Today Turku Castle runs as the Turku Castle Museum, Finland's most-visited museum with roughly 200,000 visitors a year. Its attic exhibition rooms trace the history of everyday life in Turku and the castle itself, while the keep's prisons and underground passages give a darker glimpse of centuries as a fortress, armoury and prison. We handle the ticketing so your date-specific admission is confirmed before you arrive — one less thing to plan once you're in Turku.
