The site where Kaggeholm Palace is located was first mentioned in a document in 1287. During the 1500s the farm was owned by members of the families Grip and Bååt. The farm was originally called Vettersjö, but was named by Swedish Count Lars Kagg (1595-1661) who bought the manor during 1647. Kagg was a political ally of King Gustavus Adolphus, a member of the Privy Council of Sweden and Field Marshal during the Thirty Years' War.
The chateau-style mansion was built in 1725 and designed by Nicodemus Tessin the Younger. Since 1939 it has been owned by the Swedish Pentecostal movement and is used as a training center by nearby Kaggeholm College.
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.
