Valmont Abbey (Notre-Dame-du-Pré de Valmont) was a Benedictine abbey founded in 1169 by Nicolas d'Estouteville with Benedictines split off from Hambye Abbey. It never held more than 25 monks and was destroyed and rebuilt several times, with the abbey church only truly completed in the 16th century – countess Marie II of Saint-Pol is buried in it.
The abbey buildings were built from 1678 to 1782 under Louis de La Fayette (1634–1729), commendatory abbot, who tried to introduce the Saint Maur reforms to the abbey. It was finally reformed in 1754 by the Maurists and was rebuilt during the second half of the 18th century, until the French Revolution, when it was dissolved – its monks were dispersed in 1789 and its buildings sold off to private owners in 1791.The painter Eugène Delacroix often holidayed at the Valmont manor house and the abbey ruins inspired his drawing Ruines de l'abbaye de Valmont, now in the musée du Louvre. The abbey became a monastic site again in 1994, re-founded by Benedictines from Notre-Dame-du-Pré at Lisieux and re-dedicated in 2004.
Its chapel and surviving ruins of other parts of the abbey were classed as a historic monument in 1951 and the facades and roofs of all the abbey buildings were made historic monuments in 1965.

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.
