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:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
