Norman heritage
A neo-classical architectural treasure
The Château du Buisson de May, built in 1781 by the famous royal architect Jacques Denis Antoine — also creator of the Paris Mint (Hôtel de la Monnaie de Paris) — is a remarkable example of French neo-classical architecture, square in plan with four square towers at the corners.
Located in Saint-Aquilin-de-Pacy in the Eure department, this monument was listed as a Historical Monument in 1994. The estate opens its doors for guided tours by appointment from May 1st to September 30th. It also welcomes weddings, private events and photo shoots.

A brief history
Three centuries of Norman heritage
The Lordship of Buisson de May has been documented since the 15th century. It belonged for almost 300 years to the de Bordeaux family, notables of Vernon. In 1781, Jean de Bordeaux Bargeville commissioned the present château from Jacques Denis Antoine, royal architect and member of the Académie.
Sold during the French Revolution, the estate was preserved by the Caron de Fleurey family, then Henri de Chastenay Lanty. It was acquired in 1807 by Baron Louis Philippe de Saint Albin, illegitimate son of Louis Philippe d'Orléans, who, with Marie Pierette de Tolozan, redesigned the park with the landscape architect Lalos and improved the interior decoration.
Count François Gaspard d'Onsembray inherited the estate in 1830. He lived there until 1870, when he died and the property was sold to Georges Degrand, chief engineer of the Eure department.
In 1892, Parisian banker Henri Berson bought the estate and entrusted its restoration to architect Charles Couvreux in 1895. The Labey family owned the château from 1920 to 1936, when the Caisse d'Allocations Familiales de la Région Parisienne purchased it as a holiday camp.
The château served as a British military hospital in 1939, then was occupied by German forces from 1940. The caretaker, Germaine Dumont, was arrested in 1944 for hiding Resistance fighters from forced labour. Listed as a Historical Monument in 1994, it has been undergoing restoration since 1999.

The architect
Jacques Denis Antoine
Jacques Denis Antoine (1733–1801), self-taught and son of a stonemason, is best known for his work on the Paris Mint (Hôtel de la Monnaie de Paris, 1771–1777).
He worked on the Saint Nicolas des Champs Church, designed the Visitation chapel in Nancy and the Hôtel de Jeucourt at 45 rue de Varenne (1783).
He designed only two private châteaux in France: Hercés (near Houdan) and the Buisson de May (near Évreux), plus a third now demolished near Dreux (Marville).
Elected to the Académie in 1776. The plans for the château date from 1781 and 1782.
