Gaasbeek Castle, today a national museum, was erected around 1240 to defend the Duchy of Brabant against the County of Flanders. The castle was destroyed however by Brussels city troops in revenge for the assassination of Everard t'Serclaes, which was commanded by the Lord of Gaasbeek.
At the beginning of the 16th century the Horne family constructed a brick castle on the ruins of the medieval fortress. In 1565 Lamoral, Count of Egmont, acquired the castle and its domain, including feudal rights in 17 surrounding villages. Accused of high treason by Philip II of Spain, the Count of Egmont was beheaded three years later.
In the following centuries the castle was inhabited by several noble families. It obtained its pseudo-medieval appearance as the result of a renovation during the years 1887-1898. The works were executed by the architect Charles Albert and ordered by the Marquis d'Arconati Visconti who owned the castle at that time. His widow Marie Peyrat (d. 1922) donated the castle to the Belgian state, including the art collection and the grounds.
Since 1980 the castle has been owned by the Flemish Community. The castle contains impressive art collections displayed in lavishly decorated historical rooms. A remarkable collection piece is the authentic testament of the famous painter Peter Paul Rubens The castle and its grounds (a park of 50 hectares or 124 acres) are open to the public.
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.
