Église Notre-Dame-de-l'Assomption d'Auvers-sur-Oise, Gothic church in Auvers-sur-Oise, France

The église Notre-Dame-de-l'Assomption in Auvers-sur-Oise stands on a terrace above the rue Daubigny, its light beige stone walls braced by buttresses between pointed-arch windows. A tall square tower with a clock face and two louvred pointed openings rises above the lower body, whose steep tiled roof shelters a large traceried window; a small round apse with two narrow windows sits at the lower right. The nave has a three-level elevation with a triforium, and the north absidiole remains purely Romanesque.

A first church was founded at the end of the 11th century under King Philippe I, near the royal manor; only the lower parts of the north transept, the choir and the north absidiole survive. Rebuilding began in 1137 at the initiative of Adelaide of Savoy, widow of Louis VI, starting with the eastern parts and ending with the nave, completed between 1190 and 1225. The Chapel of the Virgin was added shortly before the mid-16th century.

The church is the subject of Vincent van Gogh's painting The Church at Auvers, made in June 1890 during his final months in the village; the canvas hangs in the Musée d'Orsay in Paris. Van Gogh is buried in the cemetery of Auvers-sur-Oise, near the church.

The church stands on a terrace east of the town centre, above rue Daubigny and rue de Paris; a stone staircase built in 1615 climbs from rue Daubigny to the west portal. The terrace was the churchyard until its removal in 1858, and the square behind the chevet was laid out and planted with trees in 1875. The former deanery stands north of the staircase.

The church was first classified as a historical monument in 1856, but poorly executed interior restorations stripped much of its authenticity and it was declassified in 1874. A second classification followed in 1915. The external staircase leading up from rue Daubigny, built in 1615 under Jean-François de Berbis, lord of Hérouville and Auvers, is itself a classified monument.
