There was originally a strong fortified castle Beritzholm few hundred meters from the present Bjärsjölagård Castle. It was built by Valdemar Atterdag in the 1300s and demolished in 1526. Peter Julius Coyet bought the estate from Crown in 1720. There was a lime factory in the beginning of the 19th century and two ovens still remain. The current main building was built in Rococo style in 1766 and the southern wing in 1812. The newer addition on the estate, was built in Romantic, German style in 1849-50, on a hill just south of the old castle. It is a three-story building flanked by two square towers. Today Bjärsjölagård is a hotel.
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.
