Basilica of St Jadwiga (Church of St Bartholomew), St Jadwiga's Convent

Sanctuary of St. Jadwiga in Trzebnica

The Sanctuary of St. Jadwiga in Trzebnica, also known as Trzebnica Abbey, is a historically significant religious complex located in Trzebnica, north of Wrocław, in Lower Silesia, Poland. Founded in 1203, it was established as a convent for Cistercian nuns by the Silesian Piast Duke Henry I the Bearded and his wife, Saint Hedwig of Andechs. The foundation legend recounts Duke Henry's vow to build the abbey after a perilous incident during a hunt. The abbey received substantial land endowments from Duke Henry and became a prominent spiritual and political center.

Throughout its history, Trzebnica Abbey was a mausoleum for many rulers of the fragmented Silesian Piasts. The community of nuns experienced growth and decline, with numbers fluctuating over the centuries. The abbey faced numerous adversies, including famines and devastating fires, particularly in the late Middle Ages and early modern period. Despite periods of political turmoil, such as coming under Prussian rule in 1742, the abbey remained under the jurisdiction of the Catholic Church in Poland.

In 1810, the abbey was suppressed and secularized by order of King Frederick William III of Prussia, and its extensive buildings were later sold and repurposed, including use as a cloth factory. In the late 19th century, the site was acquired by the Knights Hospitaller and later by the Sisters of Mercy of St. Borromeo, who established a hospital. The abbey church, a basilica characterized by late Romanesque pillars and later Baroque additions, survived these changes and became the Trebnitz parish church. It houses important artworks, including paintings by Michael Willmann depicting scenes from the life of St. Hedwig, and the tomb of Saint Hedwig is located in a chapel near the high altar.
