The Château de Courances was built around 1630. In 1552, Côme Clausse, a notary and royal secretary to the King, acquired the former seigneurial dwelling at Courances, at the western edge of the Forest of Fontainebleau. His heir conveyed it in 1622 to Claude Gallard, another royal secretary, who is doubtless the builder of the present château, of an H-plan laid out on a rectangular platform that is surrounded by moat. The original château is known from the engravings of Israël Henriet and Israël Silvestre, about 1650.
In the 18th century the house was modernized by Anne-Catherine Gallard, widow of Nicolas Potier de Novion, who demolished the wall and entryway that had enclosed the courtyard. Later her granddaughter Léontine-Philippine de Novion and her husband Aymar de Nicolay further modernized the château (1775–1777) by opening new bays and applying a large pedimented center to each façade.
In 1830, the Nicolay heirs conveyed away the château, which was bought in 1872 by baron Samuel de Haber. Architect Gabriel-Hippolyte Destailleur restored the château in a Louis XIII style between 1873 to 1884. Destailleur retrieved the brickwork from beneath a layer of stucco, raised the rooflines of the pavilions and supplied zinc ornaments for the roofs. The grand internal staircase was demolished and monumental ramps of Fontainebleau inspiration were applied to the façades. A new wing with broken roofline was erected over the former kitchens to shelter the master suites, and was linked to the old wing by a gallery.
New outbuildings constructed at the same time were destroyed by fire in 1976. In the First World War, Courrances served as a hospital. In the Second World War, it was first occupied by the Germans, then by Field Marshal Montgomery, from 1947 to 1954.
Château de Courances has also an exceptional park, acclaimed as 'the epitome of the French formal garden style in which château and environment form a whole'.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
