The renovation of the castle, which was begun before the Second World War and interrupted by Finland's two wars with the Soviet Union, was completed in 1987. The completely restored castle was handed over on October 12, 1993 to the City of Turku which is entrusted with its operation for the Finnish state, its owner. The building is owned and maintained by the Finnish state and is entrusted to the use of the city of Turku. The castle functions in its entirety as a historical museum as part of the Turku provincial museum. In the main part of the castle are banquet rooms for the city of Turku, a church for the local congregation and also restaurants in both the main castle and the bailey. Today the castle is once more experiencing a heyday as it has achieved the status of being one of Finland's most visited museums.
