In 1494 Louis Picart, magistrate of Troyes and Tournaisis, friend and chamberlain of King Louis XII with whom he went to Italy, undertook the construction of the Château d'Ételan. It was built on the site of a fortress which has been destroyed under the order of Louis XI. Of the medieval construction, only the cellar, the castle wall and the guard house dating from 1350 remain.
The castle was later converted to a 15th-century flamboyant gothic mansion. The building consists of two dwellings built from layers of bricks and stones and joined together by a magnificent stone staircase dating from the first Renaissance. As integral part of the main building, the Chapel, dedicated to Mary Magdalene, include stained glass windows, wall paintings and statues which characterised the first Norman Renaissance.
History or legend tells us that several kings and famous people have spent time at Ételan like Louis XI, Frans I, Catherine de' Medici, Charles IX with the future kings Henry III and Henry IV and later Voltaire (1723–1724).
