Escaladieu Abbey was a Cistercian abbey located in the French commune of Bonnemazon. Its name derives from the Latin Scala Dei ('ladder of God'). The abbey was founded in 1142 and became an important pilgrimage stop on the Way of St. James en route to the Cathedral of Santiago de Compostela. The abbey is situated at the confluence of the Luz and the Arros rivers near the Château de Mauvezin.
The abbey was continuously inhabited by Cistercian monks until 1830 when it sold to an unknown local family. In 1986, the abbey was purchased by the Conseil Général des Hautes-Pyrénées which undertook its restoration.

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.
