Origin and history

The castle of Théribus was built at the very beginning of the seventeenth century, under the reign of Louis XIII, for a member of the family of Mornay, an aristocratic line of several estates in the region, including Fresneaux-Montchevreuil and Villarceaux. Its initial architecture, marked by pavilions and a monumental grid adorned with the figure M (initial owner), reflects the influence of large local families such as the Montmorency or the Croq. The park, originally designed in French with charmilles and buis until 1826, was then transformed into an English garden, characterized by a vast lawn and remarkable trees, including a century-old cedar. Adjacent wood still preserves perpendicular and circular aisles, four centuries ago.

The area illustrates the social evolution of the region, passing from the hands of local aristocracy (Mornay, Montmorency) to the Beauvaisian bourgeoisie from the 18th century, often linked to textile trade or the judiciary. Among its occupants, the families Serpe, Foy de Morcourt, or Lamotte are distinguished, followed later by Parisian owners such as the Mercadé or Choppin de Janvry. The castle served as a refuge for clergy during the Revolution, then was occupied by American troops in 1944-1945, leaving the estate in poor condition. Subsequently restored, it was included in the additional inventory of historical monuments in 2007, thus preserving its dovecote with traditional bolts, its interior and its park.

Charles de Mornay, wounded in Rocroi, had six military sons and a bishop of Quebec, while the park, once strictly geometric, became a romantic landscape in the 19th century. Wood, alleys and buildings still bear witness to this historical stratification, mixing seigneurial heritage, bourgeois adaptations and traces of modern conflicts. The castle remains an emblematic example of the wealthy residences of the Hauts-de-France between 1610 and 1870, reflecting the political and cultural changes of the region.
