Bishop’s Castle ruins in Kuusisto

In the Middle Ages, the island of Kuusisto provided a stronghold for the bishops of the Catholic Church in Finland. The castle served altogether 15 Catholic bishops. At its time, it was a unique building in Finland. In 1528, King Gustavus Vasa of Sweden ordered that the castle be demolished. Today, only the basement and some walls of the castle remain standing. At the castle ruins, there is a summer kiosk open weekdays from 10 am to 4 pm until the end of July.

The castle ruins are located in the eastern end of Kuusisto, surrounded by beautiful nature and the sea. You can visit the area in all seasons free of charge.
