Château de Sainte Assise is a classical 18th-century château in Seine-Port featuring a distinctive symmetrical design with a main façade flanked by two pavilions. The structure incorporates classical and Italian-inspired architectural elements and is surrounded by extensive grounds. Originally built in 1608 to replace an earlier feudal manor, this noble residence was home to prominent figures including the writer Jean de la Chapelle and Madame de Montesson. The castle, which has served various roles throughout its history, now functions as a visitor attraction with recreational activities including tree climbing and other outdoor pursuits within its charming park setting.
