The Château de Groussay was built in 1815 by the duchesse de Charest, a daughter of Louise Elisabeth de Croÿ-Havré, marquise de Tourzel, the governess of the royal enfants de France of Louis XVI and Marie Antoinette.
The Château was purchased in 1938-39 by the French aesthete Carlos de Beistegui, who enlarged it, with the professional help of Emilio Terry. Cecil Beaton's inspiration for Henry Higgins' library in My Fair Lady was the library at Groussay.
Beistegui created new gardens, inspired by the Anglo-Chinese gardens of the 18th century and by an 18th-century copper tent in the royal gardens of Drottningholm Palace in Sweden. They feature a Chinese pagoda, a labyrinth, a theater of verdure, a Tartar tent, and other follies. The Gardens are classified by the French government as one of the Remarkable Gardens of France.
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.
