In 1202 Prince Henry the Bearded, husband of St. Hedwig – according to a medieval tradition – influenced by her plea, funded a nunnery of the Cistercian nuns in Trzebnica, which was the first in the then Poland of the Piast dynasty. In 1232 Gertrude, a daughter of the royal couple, became the abbess, and the duchess Hedwig herself made this place her second home, living as a nun after her husband’s death in 1238. Formally she never joined the abbey thanks to which she had her own assets so that she could be involved in charitable and foundation activities. The feast of the patron of the St. Bartholomew church in Trzebnica, which is celebrated on 24 August, in 1242 was honoured by the fact that St. Hedwig gave the Cistercian nuns the nearby village of Zawonia which is confirmed in this document (it was probably prepared in the abbey’s scriptorium in Trzebnica). A list of witnesses includes a group of clergy and lay dignitaries, including the lord of Wroclaw, Silesian Prince Boleslaw II Rogatka, his mother duchess Anna, Henry the Pious’ widow, as well as bishops from Wrocław and Lubusz.
