History
In the heart of the Beauce region, the vast cereal-growing plateau that made the granary of France so rich, the Moulin du Paradis rises up from its familiar silhouette in Sancheville, in the Eure-et-Loir department. Built in the first half of the 18th century, it stands alone as the embodiment of several centuries of milling expertise and rural ingenuity, in the service of a land that has been devoted to wheat for generations. What really sets this mill apart from its Beauce counterparts is the sophistication of its inner workings. Unlike the region's traditional swivel mills, whose millstones generally occupy separate levels in a classical layout, the Moulin du Paradis reveals a more complex organisation and modernised equipment: millstones and ball regulators coexist on the same floor, while the Berton system wings - adopted after 1860 - bear witness to an adaptation to the technical advances of the 19th century. A visit to this mill offers a rare insight into the bowels of a preserved mill building. From the masonry base, where the central pivot rests, to the second floor where the metal shaft and its wooden spinning wheel take pride of place, each level reveals a cog, a beam, a gear that make up a remarkably coherent mechanical whole. The sieve, the cylindrical drone, the small pinion, the ring gear with internal teeth: these are all parts that transform the force of the wind into flour, according to a principle that has remained unchanged for centuries. Moved from its original location at Le Paradis to Saint-Marie following a donation to the commune in 1991, the mill has found a new lease of life in the hands of Sancheville. Maintained and enhanced, it is now a heritage landmark in this open Beauceron landscape, where the immense sky and expanses of grain form a timeless and striking backdrop.
Architecture
The Moulin du Paradis belongs to the type known as the "tower mill" or "pivot mill", a characteristic feature of the Beauce region, whose main structure rests on a stone masonry base. This sturdy base contains the central pivot, the centrepiece around which the mill's entire mechanism revolves, and is supported by false feet that ensure the stability of the whole structure. The masonry tower protects the mechanical components from the elements, while allowing the pivoting head to turn into the wind. The interior of the mill is divided into several levels of remarkable technical richness. On the first floor are the wooden drone - a cylindrical piece serving as a vertical shaft - the ball regulator (the forerunner of modern self-regulating systems, allowing the distance between the millstones to be adjusted according to the speed of rotation) and the millstones themselves, an atypical arrangement compared with traditional Beauceron pivot mills. The blutterie, used to sift the flour, completes this floor. The second floor houses the metal shaft and the wooden spinning wheel, whose ring gear with internal teeth meshes with the small pinion that transmits the driving power. The Berton system wings are the most visible technical feature of the building. Composed of mobile boards articulated on four arms, they transmit their movement via four mechanical triangles connected to the second of the mechanism's five wheels. A brake controls the speed of rotation. This system, invented in the mid-19th century, represents the pinnacle of pre-industrial milling mechanics and testifies to the determination of successive owners to adapt the tool to the best practices of their time.
