By the 11th century, the château was a medieval fortress. It has had a succession of owners, including Montrocher, de Stuer... The library features a Renaissance-style fireplace carved with a Salamander. In 1837, Durand de la Saigne du Boucheron restored the building, and in 1877, art enthusiast Armand Nivet undertook transformations, hence his initials in the main hall (fireplace and beams) and courtroom (ceiling). Inside, 13th-, 16th- and 17th-century stained glass of Germanic, Flemish and Swiss origin illuminates the windows. Owned by the commune since 1936, the building and its surroundings have been a listed site since 1946. These public spaces with their contrasting atmospheres (valleys, waterfalls, pond, park) form a picturesque landscape in the village. Visits by appointment with the Nieul et Alentours association.
