In the 12th century Muri Abbey owned a farm on the Horben hill. Then, in 1700 Abbot Placidus Zurlauben build a rest home for the sacristan on the hill. The lower Prince-Abbot Gerold Haimb had the Chapel of St. Wendelin and Ubaldus built in 1730 near the home. Between 1752-76, during Abbot Bonaventure Bucher's term of office, the house and chapel were rebuilt into their present form. In 1762 the interior was furnished with wall paintings and rococo statues by Caspar Wolf.
After the dissolution of the monasteries in the Aargau in 1841, Horgen Castle was acquired by the Canton. In 1842 it was sold to a private purchaser. Initially it belonged, together with the nearby monastery, to the National Councilman Peter Suter from Sins. From 1885-1913 it was owned by District Officer Kaspar Weber of Muri, and since 1913 by the family Borsing. In 1979-80 the castle underwent a total restoration.
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.
