The first reliable mention of Neuhausen dates back to 1292, when Bishop Christian von Mühlhausen ordered to raise a fortified castle in this location. Following the reformation of the Catholic Church in Prussia in 1525 the castle became a property of Albrecht Hohenzollern of Brandenburg. The Duke had the castle completely redesigned, converting it into a suburban hunters manor. In 1550, when the Duke had made a decision to marry, he gave the manor as a wedding gift to his fiancée, Anna Maria of Brunswick.
In 1814 Neuhausen was donated by King of Prussia, Frederic Wilhelm III (1770-1840) to General Frederic Wilhelm von Bülow (1755 - 1816) in recognition of this heroic deeds during the wars with the French Emperor, Napoleon I. After the general's death the castle was inherited by count Luckner and then it became a property of general Bon.
In 1945, the rooms of the manor were occupied by a construction company. Today, the ruined castle is truly a depressing sight. No preservation work has been done in the castle for at least a hundred years.
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.
