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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
