Pelplin Abbey
Pelplin Abbey is predictably the main reason why people come here. It dates back to 1258 and is a huge monastery. It is now a fully functioning cathedral church, and visitors can attend the poignant Sunday service here. Since 1824 the church, known as Pelpin Cathedral (officially the Church of the Assumption of the Blessed Virgin Mary), has been the cathedral of the Roman Catholic Diocese of Pelplin.
