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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
