This Jesuit monastic complex is considered to be the most beautiful Baroque edifice in Poland. A Baroque gateway (18th c) leads visitors and pilgrims into the Marian sanctuary. The three-nave basilica has a very impressive and richly adorned interior. The Baroque organ, built in 1721, has figures of saints and angels that can be set in motion by a special mechanism. The angel on the central part of the organ plays a mandolin, while the cherubs turn.
