In the middle of the 15^th Century the town with the castle was again in Polish hands. The Sztum’s main tourist attraction are the remaining fragments of the Teutonic castle and mediaeval city walls. In the castle there is a brotherhood of knights, and the castle courtyard is used as a venue for open-air painting. The town part of Sztum consists mainly of the 19^th-Century monuments. Those worth mentioning are St. Ann’s Church, which comes from the late Middle Ages, but its present shape was formed at the beginning of the 20^th Century, a former evangelical church erected on the site of the old town hall – the seat of the present local museum – and a water tower of 1911. The All-Poland Prison Art Exhibition, connected to the prison in Sztum, which opened at the beginning of the 20^th Century, may be considered as an attraction.
