Sanktuarium Swietej Jadwigi Slaskiej

Sanctuary of St. Jadwiga in Trzebnica, also Trebnitz or Trzebnica Abbey, is a convent for Cistercian nuns in Trzebnica, north of Wroclaw, in Silesia, Poland, founded in 1203. It become abandoned for some many years inside the 19^th century, after which became taken over by means of the Sisters of Mercy of St. Borromeo in 1889. The abbey became established by using the Silesian Piast duke Henry I the Bearded and his wife Saint Hedwig of Andechs, confirmed by means of Pope Innocent III. The legend of its foundation relates that after Duke Henry whilst out searching fell right into a swamp from which he couldn't extricate himself.

In return for the rescue from this perilous position, he vowed to build the abbey. With Hedwig's consent, her brother Ekbert of Andechs, then Bishop of Bamberg, selected the first nuns that occupied the convent. The first abbess became Petrussa from Kitzingen Abbey; she was observed with the aid of Gertrude, the daughter of Hedwig. The abbey was richly endowed with lands through Duke Henry. When Hedwig became a widow in 1238, she went to live at Trzebnica and become buried there.
