St. Marx Abbey was a Benedictine nunnery in Gueberschwihr in Alsace, founded in about 1105. Since 1845 it has been the principal house of the Sisters of St. Joseph of St. Marc, rebuilt in 1852 after a disastrous fire.
Before the foundation of the nunnery there had been a community of monks on the site, which came to an end after a serious fire. Abbot Theoger of St. George's (1088-1119) replaced it with the nunnery, which was made subordinate to St. George's in 1184, according to a deed of Pope Lucius III. In about 1400 a monk of St. George's was mentioned as the prior here, as were possessions of the nunnery in Geberschweier and Osenbach.
In 1710 a beer brewery was built there. In 1754 the priory was transferred from St. George's to Ebersmünster Abbey in Alsace.
In 1845 the premises, empty since the French Revolution, were used by Abbé Pierre Paul Blanck to establish a women's community under the Benedictine Rule combining the veneration of the Holy Sacrament with manual labour and the care of orphans. The buildings burnt down in 1852 and the difficulties facing the new community were so great that it seemed impossible for it to survive. Against all odds it did continue and was constituted as a formal order on 9 October 1868 with the election and appointment of Sister Maria Xavier as superior.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
