Göksholm is the oldest privately-owned building in Sweden that has been continuously inhabited.
In the middle ages Göksholm was just a fortified castle with a large tower. Its oldest existent parts have been dated to the 13th century. It was built (rebuilt and enlarged) during the Middle Ages through six different stages.
After a fire at the end of the 16th century, the building was modernized according to that period's style, getting a more regular plan, bigger windows and details in the Dutch renaissance style. Despite the thorough renovation, the medieval base structure remains. A painted inner ceiling from the time of this renaissance renovation exists with 121 cassettes which is remarkably well preserved today.
Under the 17th century owners, Baron Knut Kurck and Baron Fleming, the castle was encrusted with portals, and circle-patterned outer buildings. Lars Gustaf Tersmeden had the ceiling renovated in 1801. This was the last big change in its structure. Some facade details were changed in the 1950s.
Historically Göksholm is famous for the popular uprising's leader Engelbrekt Engelbrektsson, the leader of the government, having been murdered on its lands in 1436 by Måns Bengtsson, the son and heir of the then owner of the castle.
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.
