In the XVII° century, Jean-Louis de Courbon, the Jacques’grandson, transforms La Roche Coubon as one can see in the picture of the Dutch painter Jan Hackaert (1628-1685).
The château is at the height of its beauty, surrounded by sumptuous French gardens which saw the light of day before those of Versailles. The main body of the château is opened up to daylight : wide windows are installed to east and west and the roof has Mansart openings. An elegant balcony is constructed on arches “en anse de panier” supported by five Tuscan pillars.
A double staircase goes down to the gardens along the border of which the lazy little river Bruant wanders and throws itself, a few kilometers further on into the Charente. The surroundings are harmoniously integrated with the esplanade supported by a high wall above the water course. Shrubs encircle this spacious terrace bordered by two Louis XIII pavilions covered in fish-scale tiles, a miracle of elegance.

Another precious document, signed towards 1710 by Claude Masse (military architect to Louis XIV) shows that the east part of the main building and the two strong towers no longer exist. It is thought that a large part of the building was destroyed by fire.

The rest of the eighteenth century does not see many owners except the marquis Sophie-Jacques de Courbon who, in 1785, for 240.000 pounds regained the family property. He settled in the château, undertook a series of improvements : the hugestone staircase leading to the upper storeys and, in the gardens; the cast iron gates with their coat of arms.

After the revolution, the marquis not having emigrated, the château was not sold as state property. In 1817 his daughter auctioned it. Then the long sleep of La Roche Courbon began until its second re-birth in the twentieth century.
