There has been a manor house on the site of Keila-Joa manor (Schloss Fall) since the 17th century. The present manor house was built in 1831-1833 and designed by St. Petersburg architect Andrei Stackenschneider. The manor represents one of the earliest examples of neo-Gothic architecture in Estonia. It was built for the family of count Alexander von Benckendorff (whose graves can be found in the park adjacent to the manor) and the building saw many prominent guests during the Imperial years, among others the Russian royal family, famous soprano Henriette Sontag and composer Alexei Lvov.
From 1927 to 1940 it was used by the Estonian Ministry of Foreign Affairs. During the Soviet occupation it was used by the Red Army. The centre of the manor now belongs to the Estonian Ministry of Foreign Affairs, but is not being used currently and is awaiting restoration. In 2010 the manor was sold into private hands.
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.
