This postcard shows the interior of Turku Castle. More precisely, that's the chapel in the castle :)
The Turku Castle, (Finnish: Turun linna, Swedish: Åbo slott) dating from the 1280s, is a monument of Finnish history. Together with the Cathedral of Turku, Turku castle is one of the oldest buildings still in use in Finland. Turku castle is the largest surviving medieval building in Finland, and one of the largest surviving medieval castles in Scandinavia. This national monument standing on the banks of Aura river has experienced many stages for more than 700 years.
A start was made on building the castle in 1280. It was originally designed as a military fortress. During the next two centuries its defences were strengthened and living quarters were added. The castle served as a bastion and administrative centre of Eastland, as Finland was then know during it's time under Swedish rule. Turku Castles significance as a defensive fortress and administrative centre varied throughout the ages according to the political situation. Today the castle is once more experiencing a hayday as it has achieved the status of being one of Finland's most visited museums.
