Château d'Auvers, Heritage monument and château in Auvers-sur-Oise, France.

The château d'Auvers is a 17th-century stone building in Auvers-sur-Oise, with a pale cream facade, dark grey slate roofs and a taller central block flanked by lower wings. Its steep hipped central roof carries a flat-roofed square lantern with a small spire, and three floors of tall rectangular windows are set evenly across the front. Two dormer windows sit in the left wing's sloped roof, and small sculpted trees stand along the front within a low wall.

The château d'Auvers was built in 1635 by the Italian banker Zaboni Lioni, a member of Marie de Médicis's entourage. At the end of the century Jean de Leyrit, king's counsellor and treasurer general of France, turned the Italian pavilion into a French château and had the estate made a fief. In 1756 the north Louis XIII facade was kept while two pavilions were added to the south; in 1765 the estate passed to Prince Louis François de Bourbon-Conti, whose monogram survives on the nymphaeum. The Val-d'Oise general council bought and restored the site in 1987, and the château, its staircase and park were inscribed as monuments historiques on 23 July 1997.

The château houses exhibitions about art history and the artists who stayed in the region. Its rooms reveal how creators found inspiration in these surroundings.

The château is reached from the centre of Auvers-sur-Oise, and the park and gardens are included in the visit alongside the exhibition rooms. The permanent exhibition opened in October 2017 and is translated into nine languages. The château takes part in the Nuit des musées in mid-May, Rendez-vous aux jardins in the first weekend of June and the European Heritage Days in the third weekend of September.

The château's south facade and gardens were redesigned from 17th- and 18th-century engravings, with boxwood embroidery and fountains. The nymphaeum still carries the monogram of Prince Louis François de Bourbon-Conti, who restored its decoration and stayed mainly for hunting after buying the estate in 1765.
