Castles have dungeons, normally...

Of course the duckies also stopped by in Turku, Finland on their big north tour! This picture was taken at Turun Linna ( Castle of Turku). It was build in the 13-hundreds and is the biggest middle-age building that exists in Finland. You can visit this place and check out the castle itself (with guided tours in different languages every now and then, too), as well as the nice museum inside. It's worth it!
