Château de L'Échelle origins are unknown. A first castle at this site was probably founded in the 13th century. In the 15th century a band of Armagnacs, outlawed supporters of Charles, Duke of Orléans, during the Hundred Years' War, settled in L'Echelle Castle and ravaged the area.
In 1594, Antoine de La Marche des Contes became Lord of L'Echelle by his marriage to Anne de Maucourt. Antoine, Governor of Sedan between 1599 and 1640, rebuilt L'Echelle Castle and gave it its present appearance. In 1642 Spanish troops plundered the village and attacked the castle. The castle walls still bear traces of this attack.
In 1730 the castle was acquired by the Chapter of Reims and transformed into a farm. During the French Revolution it was confiscated and sold as Bien Nationaux to a local hatter, Simon Pottier. He ceded the castle to the local community. The castle then became the town hall, a school and lodging for the head teacher.
At present L'Echelle Castle is still property of the village and houses a small local history museum.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
