In 1700, Charles Jacques Adrien de Mullet, seigneur of Wancquetin demolished the remains of the small castle, knocking down the motte and filled in most of the moat. He then build a chateau, using white bricks and stones, enclosed by large garden walls.
In 1749 the castle was completed by the laying out of a wide terrace (500’ long by 40’ wide) on which there were two guns donated by Louis XV. During the French Revolution, the cannons were melted down and thrown down a well. In the 19th century, they were found and returned to the Diesbach family.
In 1789, the castle was looted and destroyed during the Revolution, leaving no trace of the edifice. The stones and bricks of the castle were used by the locals to construct homes which were in turn destroyed during World War I.
In the 19th century, the land stolen and sold during the French Revolution was restored to the Diesbach family.
