The Knighthood Building was built by von Dellingshausen at the end of the 18th Century and today, it accommodates the County Government of Saaremaa. At the beginning of the 19th Century, the house belonged to the Nobility of Saaremaa, then in 1912, to the Noblemen's club. The County Government of Saaremaa bought the house in 1920. The foundation of the building is symmetrical, with a high socle floor. The façade is proportionately divided by three protuberances, the central of which is crowned by a bow-shaped pediment. The balcony with dolomite marble columns and an iron balustrade decorates the façade.
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.
