Dragsmark Abbey was a Premonstratensian canonry, also known as Marieskog in Norwegian. It was founded before 1260, with the support of King Håkon Håkonsson, and was dedicated to the Blessed Virgin Mary. The abbey was very wealthy in its heyday and ran a prestigious school, but declined during the 15th century, and as early as 1519 was in the control of a lay administrator, the first monastery in Norway to be secularised. With the Reformation the Crown granted it to a tenant in 1532, with a condition that the remaining canons had to be maintained. The buildings fell into disrepair, and in 1610 were used as a quarry for stone for the construction of Båhus Fortress.
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.
