Kuusisto castle ruins

In the Middle Ages, the island of Kuusisto was selected as the site for a stronghold for the bishops of the Catholic Church in Finland.  The fortified castle served as their sanctuary until the Reformation. The castle was governed by altogether 15 Catholic bishops. Over the course of about 200 years, the castle was built in stages and used as a residence and fortress; it was a unique building in Finland. In 1528, King Gustavus Vasa of Sweden ordered that the castle be demolished. Today, all that remains is the basement and some walls.
