Oliwa Archcathedral was built on the site of a Cistercian monastery, founded by monks brought here by the Pomeranian dukes in the 12th century. The oldest parts of the church are more than eight hundred years old. The audio guide leads you through the interior of the cathedral and tells the story of its history, altars and chapels. It pays particular attention to the famous organ from the late 18th century, built by Brother Michael – Jan Wulf of Orneta. The recordings are available in Polish, English and German.
