The medieval Kuusisto Bishop’s Castle was built as a refuge for the high-ranking clergy of the Catholic Church in Finland, on the shore of Piikkiönlahti Bay. In the early 1500s, the castle was one of the largest bishop’s castles in the Swedish realm and the center of spiritual life and political power in Catholic Finland. The grand castle was filled with everyday luxuries and modern solutions from abroad: it even housed what is considered Finland’s first indoor toilet and tiled stove. The castle’s story ended when King Gustav Vasa ordered it to be demolished after the Reformation in 1528. Vegetation took over the once magnificent castle, leaving only ruins of its former glory. The Kuusisto Bishop’s Castle ruins are open to visitors free of charge all year round. The site is suitable for a family day trip.
