The New Castle of Ansembourg is one of the castles belonging to the Valley of the Seven Castles. In 1639, industrialist Thomas Bidart built the central part of today's castle as a comfortable house surrounded by walls and towers, two of which still stand. Originally from Liège in Belgium, Bidart, who was a pioneer of Luxembourg's iron and steel industry, named the building Maison des Forges (House of the Ironworks). During the Thirty Years' War, he tapped the region's many water sources and exploited its timber and iron, manufacturing arms at a foundry close to the old castle. As a result, his family prospered, earning rights to the title of Lords of Amsembourg which had belonged to the Raville family until 1671.
It was the de Marchant family who, after inheriting the property by marriage, undertook its astonishing transformation into today's modern-looking castle. In 1719, the courtyard was extended with two wings on either side of the original building. The southern gable was enhanced with a magnificent arch where four statues represent the four continents. Fitted with two small towers, the new façade overlooked the gardens which were connected to the castle through an arcade. The first-floor balcony above the porch provided an excellent view of the gardens, complete with flowerbeds and a fountain. Between 1740 and 1750, Lambert Joseph de Marchant et d'Ansembourg further improved the gardens and extended the buildings on the north side of the main courtyard so that they could be used as stables and lodgings for the castle staff. In 1759, Count Lambert Joseph added the impressive Baroque gateway bearing the arms of de Marchant of Ansembourg and Velbruck.
Since 1987, the castle has belonged to Sûkyô Mahikari who has undertaken substantial renovation work with the assistance of Luxembourg's Service des Sites et Monuments nationaux. Initially work was centred on reinforcing the foundations and walls and on restoring the staircase of honour on the upper terrace in the gardens. From 1999, the statues and the fountains in the garden were repaired while the roofs over the two wings and the central section were rebuilt. Work is now concentrated on restoring the oldest part of the building which dates from the 17th century.
The castle gardens are open to visitors from 9 am every day. The castle also hosts a number of cultural events during the year.
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.
