In 1411, a quarrel broke out between the Count of Tonnerre (Louis II of Chalon-Arlay) and the Duke of Burgundy (John the Fearless).

For example, her brother, Antoine III of Clermont, entrusted the architect Sebastiano Serlio to building him a château in Ancy-le-Franc, near Maulnes, about 25 years earlier.

With the signing of the Edict of Amboise in 1563, France enjoyed a brief period of peace from internal religious wars, allowing for a large-scale project, such as building the Château de Maulnes, to come to fruition.

In February 1568, following a period of religious unrest, the Prince of Conde's army occupied the suburbs of Tonnerre and besieged the city, relenting with the payment of a ransom.

In November, the Catholic troops seized Noyers (Yonne), and about a year later the army of Marshal de Cosse arrived and restored the peace in Tonnerre.

The second project, constructing the adjoining buildings, may have started in August 1570, after the departure of Crussol who joined the French court in later life.

Once again a widow, Louise de Clermont spent her remaining years between Paris, Tonnerre, Ancy-le-Franc and Maulnes.

With respect to the ownership of the château, in 1658 a judgment of parliament sided with the younger brother Roger, Marquess of Cruzy.

Between 1650 and 1670, In 1647 Roger returned from the armies of Flanders and between 1650 and 1670 he made modifications and repairs to château de Maulnes.

Between 1683 and 1685, François-Michel le Tellier, Marquis de Louvois bought Tonnerre county from François-Joseph Clermont, the grandson of Francis and the grand-nephew of Roger.

In 1721, the eldest son of Louvois, Michel-François Le Tellier marquis Courtanvaux, inherited Tonnerre County, but he died soon thereafter.

His daughter, Anne-Louise de Noailles, received temporary guardianship until his two-year-old son, Francis Tellier Caesar Courtanvaux, became an adult.

In 1723, the royal council of finance authorized timber to float from Maulnes to Paris by the Armançon, Yonne and the Seine rivers.

This industry transformation significantly changed the landscape of Maulnes with the gradual clearing of the forest and the growth of the community.

He died in debt four years later and his widow Jeanne Marie Henriette Bombelles Victory supervised the estate on behalf of her two-year-old son.

In 1819, production doubled and the local glassware industry was employing a hundred workers, in addition to the loggers and valets.

The château, without the land was purchased by the Friends of Maulnes Company and for the first time, a large backup funded plan was implemented.

For four years, the research focused on various themes such as the relationship between the château and the  Maulnes forest and the hydrogeological study of the site.

This initial research identified for the first time the most pressing issues needing to be addressed in the prevention of further deterioration and restoration of the château.

While the initial work has saved Maulnes and created a tourist attraction, it will take many more years before the château and grounds are fully restored to their original, 16th-century condition.

The plans of Du Cerceau shows a floored gallery with five arches leading to an open-air fixed bridge supported by four columns and a moveable gateway.

The surviving traces show a forest backdrop and several female figures, possibly a representation of the legend of Diana.

This level was the main floor of activity, recognizable by the greater ceiling heights and two Doric columns that adorn it.

From the description of Androuet du Cerceau, ceilings of this floor were quite remarkable, especially the enrayure-style box struts that are aligned diagonally with the room walls.

At the top of the château is a terrace surrounded by five chimney stacks, forming belvedere with a room for a roof lantern in the center.

The small rubble, used for interior wall siding, came from astartes limestone deposits located a few hundred meters from the château.

Closing the walls, including the most distant part of the château is in a semicircle, surrounded by a hedge and a grass glaze.

On the mode of "palazzo in fortezza" Italian (a palace in a fortress), it was probably to protect themselves from common disorders in these times of civil war.

The current theories suggest a terrace wall separated the enclosed basin from the rest of the garden, interrupted by an access staircase.

The plan of Du Cerceau could have corresponded to a project of later development that never came to fruition due to the abandonment of the site or the death of Antoine de Crussol.
