Gammel Estrup Manor as we know it today was built in 1490, but excavations have revealed evidence of earlier constructions also mentioned in texts under the name Essendrup dating back to 1340.
The construction of Gammel Estrup was started by the contentious Lave Brock. But it was his great-grandson, Eske Brock who most people today think of in connection with the manor. Eske Brock was a nobleman and close friend of King Christian IV to whom he also served as a minister. Through Brock's detailed diaries we know a great deal about the King's life.
From 1930 the manor has served as a museum, showing the development of Danish nobility through the ages. The surrounding buildings support the museum, the nearby apple plantation and a horticulture research center.
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.
