There was a small fort in Bettembourg as far back as the 10th century. A tower was added later but was removed when further extensions were made in the 17th century. A second castle was built around 1733 by Lothaire de Zievel and his wife Appolinaire-Agnès-Elisabeth de Haagen Motten. The neighbouring stream known as the Düdelingerbach was probably one of the reasons they chose the site. The rather austere architectural style was typical of the period, especially as the building was designed in the interests of farming.
The oldest part of the castle is the south wing which housed stables and barns. The north wing, now the main part of the U-shaped complex, was added later. In about 1759, Jean-Henri de Zievel charged the architect Rousselet de Boulay with major restoration work. In 1765, on the death of the last member of the De Zievel family, the castle fell into the hands of the castle manager, Marc-Antoine de Verniolles. Various proprietors followed including members of the Hohenzollern-Hechingen-Haigerloch family (1780), Charles Joseph Collart de Donnea, owner of the Dommeldange iron works (1807), followed by various members of the Collart family until 1971. When his wife, Daisy Collart-Weber, died in 1969, August Collart decided to sell the property. The commune of Bettembourg bought the property in 1971 and, after undertaking extensive restoration and reconstruction work, opened the building as the Bettembourg town hall in 1991.
The castle now serves as the commune's administrative building and as the town hall of Bettembourg. One of the important transformations has been the creation of a large cultural room or art gallery. The castle's ornamental wooden panelling and its many fireplaces are of particular interest. The large park surrounding the castle is also 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.
