Origin and history

The castle of Denainvilliers, located in Dadonville in the Loiret, has its origins since the 12th and 13th centuries, although the current remains date mainly from the 14th, 17th, 18th and early 19th centuries. In 1621 Antoinette Jacquelot, heir of the estate, married Claude Duhamel, a noble anobli in 1635 under Louis XIII. The latter began the demolition of the old castle to build a new body of central houses around 1625, followed by the two pavilions (1632-1638) and the chapel, consecrated in 1647. These transformations mark the advent of a more modern architecture, reflecting the ascending social status of the family.

In the 18th century, the castle became the place of residence and research of scientist Henri-Louis Duhamel du Monceau, grandson of Claude. He installs scientific instruments, including solar dials and a gnomonic ensemble, and conducts experiments on grain conservation, digging vats in cellars and planting exotic trees in the park. In 1750 he built a "Polish-style" mill dedicated to these studies, a symbol of the agricultural innovation of the time. These developments bear witness to the spirit of the Enlightenment, combining practical science and state management.

The 19th century brought major restorations, notably in 1805, where the interior decor was replaced by an Empire style, partially erasing the traces of Louis XIII. The mill, disused, was transformed into a dovecote after the destruction of its mechanism. After a period of degradation, the castle was restored in 1956. Today, it retains protected elements such as the oval room on the first floor, the facades, the stairwell with its sundial, and the commons, classified or inscribed in the Historical Monuments between 1969 and 1988.
