First mentioned in 1519, Härgla manor belonged to the von Maydell family in the Middle Ages. Later it had many owners, till the von Wetter-Rosenthal family obtained it for a longer period in the 19th century. The two-storied main building has been built in several parts during 17-19th centuries. The building has one of the most beautiful Classicistic pillar porches of the beginning of the 19th century in Estonia. From the 1920s till 1960s, the building was in 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.
