Deutz Abbey was founded in 1003 on the site of a Roman fort by the future Saint Heribert, Archbishop of Cologne, close adviser of Emperor Otto III. Heribert died in 1021 and was buried in the Romanesque church he had had built here. The theologian Rupert of Deutz was abbot during the 1120s.
The abbey had extensive properties, but its strategic position by the Rhine exposed it to involvement in fighting, and it was destroyed in the 14th century and again in the 16th century. It was dissolved during the secularisation of the Napoleonic era, but the abbey church, now known as Alt St. Heribert, became a parish church in 1804.
In World War II it was heavily damaged and only the ground floor and remnants of the Romanesque cellar were preserved. Reconstruction took place in the 1970s. Today the former abbey accommodates an old people's home run by Caritas. Notable are the mural paintings by the artist Werner Weber. The former abbey church of Alt St. Heribert is now used by the Greek Orthodox community of Cologne, and has been superseded as a Roman Catholic parish church by Neu St. Heribert, which now houses the shrine of Saint Heribert.
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.
