Sights and Activities

  • The medieval Kuusisto Bishop's Castle was built as a stronghold for bishops of the Catholic church in Finland, on the shore of Piikkiönlahti bay. The castle was built, repaired, extended and used for a couple of centuries. In fact, in the early 1500s this was one of the largest bishop's castles in the Swedish realm. King Gustav Vasa ordered the castle to be demolished in 1528, after which the once grand castle became overgrown.
