The castle also had an armoury that equipped up to 800 soldiers. Outside the walls were large orchards and gardens.The Visingsborg Castle was empty for several years after the death of Count Per Brahe the Younger in 1680. Later, in the early 18th century, it was used as a camp for Russian war prisoners. It is said that it was these prisoners who finally burnt down the castle in 1718. What is left today is only the left wing.

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.
