Écouen : Domaine du Château d'Ecouen, currently Renaissance Museum

Renaissance style building, built between 1538 and 1555 for the constable Anne de Montmorency by the architect Jean Bullant. The sculptures of the building are made by Jean Goujon. The castle was surrounded, at its northeast corner, of an enclosed garden. The retaining wall of the access terrace shows the location of a niche on the south wall of this garden, which has not existed since at least the end of the 17th century. The cave, commanded by the constable at Bernard Palissy in 1556, was not finished. In the 19th century, the chroniclers located it near the Madame fountain. Between the end of the 18th century and 1709, while the property belonged to the son of Condé, Jules Hardouin Mansart designed a park which is the ancestor of the current state of the premises. The gardener organized the park around two perpendicular axes which meet in front of the west facade of the castle, accentuated by a row of trees. Some alleys lead to belvederes and revolve around roundabouts. A terrace in front of the western facade has a committed flowerbed, divided into three sections. As an extension north, an opening connects the park to the village. An alley bordered by two rows of trees offers a majestic entrance to the castle. The old hydraulic installations have disappeared. A plan of 1894 mentions more recent landscaping, such as a palm game and a ballroom. La Fontaine Hortense is the main development of the 19th century, erected by Eugène de Beauharnais.
