The Château du Grand Jardin was a maison de plaisance attached to Claude de Lorraine, duc de Guise, who built it between 1533 and 1546 as a grand pavilion designed for fêtes and entertainments. The château formed an annex to the medieval castle overlooking Joinville, a stronghold of the House of Guise that was demolished at the French Revolution.
In addition to its grand festive hall, which dominated the interior, were a suite of semi-private rooms to which the duke and duchess could withdraw with their most honored guests; they included a chamber preceded by its antechamber and a more private garde-robe within, but no bedrooms, as the seat of the Duke, the château de Joinville itself, was so near at hand. The Château du Grand Jardin functioned as a banqueting house on the grandest scale, a fit demonstration of the power and prestige of the head of the House of Guise.
The site, partly in ruins, was purchased at the beginning of the 1980s by the conseil général of Haute-Marne. The building was restored, and the grand park created in the 19th century has been restored and replanted.
The site has also reacquired its original vocation as a place of culture: concerts of classical music are presented at the Grand Jardin, expositions of contemporary art, and colloquiums. The château du Grand Jardin is currently a member of the European network of Centres culturels de rencontre.
The plan of the château, surrounded by its moat in the usual French manner, comprises a rectangular corps de logis without wings or outbuildings. Richly ornamented, it combines elements of Italian architectural style, under its prominent French slate roof with dormer windows.
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.
