The Blessed Virgin Mary Church - The castle chapel existed from the first stage of the castle construction in the end of the 13 th century. Due to the change of function and the extention of the fortress after moving the Teutonic state capital to Malbork in 1309, the chapel, which at first occupied only a half of the wing, was elongated and a polygonal presbytery was built on from the East. The date of the work completion – 1344 – was fixed with a consecration inscription inside the chapel.
