Château de Créminil was built in 1443 by La May family to the site of older fortification (destroyed by English Army). In 1540 Créminil was owned by Hugues de Buleux (advisor to the regent of the Netherlands and grand bailiff of Aire). After the castle was burned in 1543 it was rebuilt in the 17th century.
In 1670 it was owned by Antoine de Wignacourt and from 1687 till the Revolution by the Merchiers family. Until 1978 Créminil Castle was owned by a Mrs Lhéritier whose family had it since the Revolution.
This late medieval castle consists of an irregular polygon with twelve sides, built on a small mound surrounded by large round moat fed by water from the Laquet stream. In the 18th century 3 sides of polygon to the south were torn down and replaced by a terrace lined with stone balusters to provide a better view of the surrounding gardens. Also the facades of the buildings on the courtyard were rebuilt.
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.
