Lyse Abbey was founded in 1146 by Sigurd, Bishop of Bergen, on farmland that he owned, as the Christianisation of Norway was nearing completion. The first monks were brought from Fountains Abbey in Yorkshire, England. This was the first Cistercian monastery in Norway and was modelled on others built in England and France.
As with all Cistercians, the monks took a vow of poverty. Renouncing all sources of income except from farming, they developed considerable skill in farming operations and management. Over time, this led to the abbey acquiring many other farms in the area, making it ever more rich and powerful. In all, the monastery had about 50 other farms in Os with at least as many more in other areas.
The abbey was dissolved in 1537 when Christian III of Denmark decreed Lutheranism to be the state religion of Norway. The abbey’s possessions were confiscated, becoming the property of the King. Over the next two centuries, the stones of the monastery structures were gradually removed and contributed to buildings such as the Rosenkrantz Tower in Bergen, and Kronborg Castle in Helsingør in Denmark. Some stones were shipped as far as Germany.
The ruins are protected as a national monument and archaeological work to preserve and record the site continues. The monastery is a well-visited tourist site with good nature walks nearby. It is common for couples today to be married at the ruins, or at least to have wedding photographs taken there.

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.
