Turku Castle

"Turku Castle (Finnish: Turun linna, Swedish: Åbo slott) is a medieval building in the city of Turku in Finland. Together with Turku Cathedral, the castle is one of the oldest buildings still in use and the largest surviving medieval building in Finland. It was founded in the late 13th century and stands on the banks of the Aura River. The castle served as a bastion and administrative centre in Eastland, as Finland was known during its time as a province of Sweden. Only once did the castle figure in the defence of the realm, when Russian invaders from Novgorod destroyed Turku in 1318. It more frequently played a role in internal struggles for power within Sweden and the Kalmar Union. The castle's heyday was in the mid-16th century during the reign of Duke John of Finland and Catherine Jagellon. That was when the Renaissance Floor and King's and Queen's hall were built, along with other features. It lost its status as an administrative centre in the 17th century after Per Brahe's period as governor-general of Finland came to an end. Turku castle is today Finland's most visited museum, with attendance reaching 200,000 in some years. In addition, many of the larger rooms are used for municipal functions."

This is a MUST when visiting Turku! one of the oldest and most beautiful buildings in Turku is the Turku castle, unfortunately it was never open when I was there but I was able to mooch around the outside and around the grounds, the building is stunning with the classic horror look as if there are 100 ghosts staring at you when you're walking around. 

From here you can see the marina, with ships docked, boats and people fishing. 

Turku castle is also very close to the boat museum.
