In the gardens cabinets de verdure shaped into niches that held sculptures were clipped into the dense woods, fitted with trelliswork dadoes to fill in their sparse bases.
About 1680, Adam-Frans van der Meulen painted a landscape view of a promenade en calèche with Louis XIV, Queen Marie-Thérèse, Madame de Montespan, and the king's son and his wife, which includes in a single coup d'œil both Versailles and Clagny, showing how closely the two châteaux were located.
In 1685, the King formally made it over to her as a gift, partially for the sake of their eldest natural son, the beloved Louis-Auguste, Duke of Maine.
At her death in 1707, the Duke of Maine inherited Clagny, followed in time by his grandson, Louis Auguste, Prince of Dombes, who as it turned out became the last of his line.
When the ownership of Clagny reverted to the Crown, Louis XV gave some eleven hectares at the edge of the estate to his very religious queen, Maria Leszczyńska, who used the land to establish an Ursuline convent which was built from 1767 to 1772 according to the designs of Richard Mique.
