On June 25, her dies natalis, the Archdiocese of Gdańsk, the Archdiocese of Warmia, and the Diocese of Elbląg keep the memorial of Blessed Dorothy of Montau — obligatory in Elbląg, where she is named patroness. She was born in 1347 in Mątowy Wielkie near Malbork, married young to a Gdańsk armorer, and widowed after three decades before she came to the cathedral town of Marienwerder, now Kwidzyn, in 1391.
In 1393 she asked the cathedral chapter to wall her into a small cell against the church's south wall. She lived there as an anchoress for the last thirteen months of her life, guided by her confessor Johannes von Marienwerder, who recorded her visions and the stigmata that made her the only stigmatist among Poland's saints and blesseds. She died in the cell on 25 June 1394.
Her cause stalled for centuries before Pope Paul VI signed a decree of equipollent beatification on 9 January 1976, confirming a cult already nearly six centuries old. Her relics vanished during the Reformation and have never been recovered; a 2008 excavation beneath the cathedral presbytery found only an empty grave. The chapel and cell shown to pilgrims at Kwidzyn today remain the center of her cult, alongside the parish of her baptism at Mątowy Wielkie.
