Oelenberg Abbey is a Trappist monastery located in Reiningue near Mulhouse, France. It has been an important place of worship in Alsace since the 11th century but now hosts a small community.
In 1046, a priory of the Canons Regular of St. Augustine was founded by Heilwig of Dabo, Countess of Eguisheim and mother of Pope Leo IX. The latter dedicated the church in 1049. The abbey was originally a double monastery. In 1273, the nuns left for Cernay. In 1626, the abbey was handed over to the Jesuit college of Freiburg im Breisgau, then in 1774 to the University of Freiburg, until the community was suppressed and the site sold off as national property during the French Revolution. In 1825, a group of Cistercian monks from Kleinburlo Abbey, Darfeld in the Rhineland, settled in the buildings.
During the First World War, a major part of Oelenberg Abbey was destroyed by bombing on June 26, 1915. The church, the organ of Rinckenbach and the conventual buildings suffered extensive damage. The abbatial church and the convent were re-built in 1920 by architect Paul Kirchacker of Mulhouse using the remains of the church. The choir stalls carved by Théophil Klem were scrupulously restored.
During the Second World War in November–December 1944, the abbey was partly destroyed. The French artillery wanted to spare the monastery, but had to bomb an observatory built by the Germans in the bell tower of the church.
The abbatial church has Romanesque, late Gothic and Baroque elements from the 12th century, 1486 and 1755 respectively. It is adorned with a 12th-century processional cross, a 14th-century crucifix, and two statues of the Virgin Mary of the 15th and 18th centuries.
The three chapels of Saint Michael, Saint Leo and the Mount of Olives feature elements of the 12th century and of 1486, as well as a painting and a reliquary that come from Lucelle Abbey which was dissolved during the French Revolution.
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.
