Sanctuary of St. Jadwiga, also Trzebnica Abbey, is a convent for Cistercian nuns founded in 1203. The abbey was established by the Silesian Piast duke Henry I the Bearded and his wife Saint Hedwig of Andechs, confirmed by Pope Innocent III. With Hedwig's consent, her brother Ekbert of Andechs, then Bishop of Bamberg, chose the first nuns that occupied the convent. The first abbess was Petrussa from Kitzingen Abbey; she was followed by Gertrude, the daughter of Hedwig. The abbey was richly endowed with lands by Duke Henry. When Hedwig became a widow in 1238, she went to live at Trzebnica and was buried there.
Up to 1515, the abbesses were first princesses of the Piast dynasty and afterwards members of the nobility. It is said that towards the end of the thirteenth century the nuns numbered 120. The abbey also became a mausoleum of many rulers of the fragmented Silesian Piasts. In 1672 there were 32 nuns and 6 lay sisters, in 1805 there were 23 nuns and 6 lay sisters. The abbey suffered from all kinds of misfortunes both in the Middle Ages and later: from famine in 1315, 1338, 1434, and 1617, from disastrous fires in 1413, 1432, 1464, 1486, 1505, 1595, and 1782. At the Protestant Reformation, most of the nuns were Poles, as were the majority until during the eighteenth century. The abbey of Trebnitz suffered so greatly during the Thirty Years War that the nuns fled across the border on the territory of the mostly unaffected Polish–Lithuanian Commonwealth, as they did again in 1663 when the Turks threatened Silesia.
In 1742, in the aftermath of the First Silesian War and the Treaty of Breslau, Trebnitz found itself under the governance of Protestant Prussia and started to suffer from political discrimination. The last abbess, Dominica von Giller, died on 17 August 1810, and on 11 November 1810, the abbey was suppressed and secularized by order of King Frederick William III. The building, which was very extensive, was sold later and turned into a cloth factory. In late 19th century, the ruined abbey was bought by Knights Hospitaller and later by female order of Sisters of St. Charles Borromeo as a hospital conducted by the sisters.
The church, a basilica with pillars in the late Romanesque style, to which Baroque additions were made from 1741. It features several paintings with scenes from the life of St. Hedwig by Michael Willmann. After the secularisation of the abbey, it became the Trebnitz parish church.
The grave of St. Hedwig is located in a chapel to the right of the high altar, donated by her grandson Archbishop Ladislaus of Salzburg in 1267. The grave of Duke Henry I, her husband, is in front of the altar.References:
La Hougue Bie is a Neolithic ritual site which was in use around 3500 BC. Hougue is a Jèrriais/Norman language word meaning a \'mound\' and comes from the Old Norse word haugr. The site consists of 18.6m long passage chamber covered by a 12.2m high mound. The site was first excavated in 1925 by the Société Jersiaise. Fragments of twenty vase supports were found along with the scattered remains of at least eight individuals. Gravegoods, mostly pottery, were also present. At some time in the past, the site had evidently been entered and ransacked.
In Western Europe, it is one of the largest and best preserved passage graves and the most impressive and best preserved monument of Armorican Passage Grave group. Although they are termed \'passage graves\', they were ceremonial sites, whose function was more similar to churches or cathedrals, where burials were incidental.
