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).

The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
