Dorothea of Montau was a 14th-century anchoress and visionary living in Prussia. Born in Mątowy Wielkie to a wealthy farmer, she married a swordsmith from Danzig, though her spiritual life often clashed with her husband's temperament. After experiencing numerous mystical visions, she eventually moved to Kwidzyn, where she lived in a cell attached to the cathedral. Known for her extreme austerity and devotion to the Eucharist, she remained in this secluded life until her death in 1394.
