Origin and history
The mansion of the Grand-Moulin, located in Condette in the Hauts-de-France, finds its origins in the 14th century with the creation of the fief du Grand Moulin. However, today's buildings date mainly from the second half of the seventeenth century, with subsequent additions in the eighteenth and nineteenth centuries. The ensemble was once organized around a courtyard with a drinking pot, typical of the manor farms in the region. The house body, built of Baincthun stone, is flanked by two characteristic turrets: one in corbellation with a campenard housing a bell classified in 1943, the other round, pierced with murderers and capped with a flat tiles pepperpot. These elements, as well as the original drills on the west facade, bear witness to a defensive and residential architecture, inherited from the Middle Ages but adapted to the modern era.
The central dovecote tower, dated 1564, was destroyed at the end of the 19th century, as were the agricultural buildings, which disappeared at the end of the 20th century. Today, only the main house and some traces of the dependencies remain, visible on the cadastral plane of 1813. The roof, initially covered with flat tiles, was modified in the 20th century by the addition of mechanical tiles and triangular skylights. This manor perfectly illustrates the architecture of the Boulonnais manor houses, studied by historian Roger Rodière, mixing agricultural, seigneurial and defensive functions in a bocager landscape. Partially listed as Historic Monuments in 1998, it is a rare and preserved example of this rural heritage, despite the disappearance of elements such as the dovecote.
The history of the Grand-Moulin reflects the social and economic evolutions of the region: in the 17th century, a medieval fief linked to the milling of cereals, it became a seigneurial residence incorporating elements of comfort (stone logic, bell) while retaining defensive features (murder, turret). The gradual destruction of dependencies in the 19th and 20th centuries marked the decline of its agricultural role, while its protection in 1998 emphasized its heritage value. The bell in 1943, still in place, recalls its local importance, possibly linked to religious or community functions. Today, the mansion embodies the transition from medieval to modern times in Boulonnais, where manor houses served both as economic centres and as symbols of power.
