Restoration of Grand Salon de Vaux-le-Vicomte

At the centre of the Château de Vaux-le-Vicomte is the Grand Salon, around which the accomodation and gardens are organised.
The architect Louis Le Vau designed an oval room decorated with stucco, under a dome nearly 18m high, for which the painter Charles Le Brun planned to create an exceptional fresco, a true hymn to the sun,never executed. For almost 200 years, the dome remained undecorated until the palace was restored in the 1840s. A painter-decorator represented a sky dotted with clouds with an eagle in the centre. This fresco, too, was not completed and suffered from the ravages of time.
In 2020, the architectural firm RL & Associés was commissioned to restore the entire Grand Salon. The fresco, which had been fairly well executed, was covered with a reversible whitewash that would allow Charles Le Brun's drawing to be projected digitally.

Church of Saint Maurice de Gourdans (01)

Fountain of the Porte de Saint Cloud (75)

The fountain "Les sources de la Seine" located at the Porte de Saint Cloud in Paris has just been restored, after two years of work. It had been in a state of disrepair and abandonment for several decades.

Yet it is masterpiece in several respects : a masterpiece of decorative art from the 1930s by the sculptor Paul Landowski, but also a masterpiece of urban planning to create a monumental square at the gates of Paris in place of the old ramparts, and finally a technological masterpiece, as it was the first illuminated fountain in Paris, inaugurated for the 1937 Univeral Exposition.

Château de la Chaize - Réalisation du portail d'entrée

It is extended on both sides by a half-moon materialized by a wrought iron gate mounted on a stone base. The access path has been requalified and bordered by an alignment of ash and lime trees.
