A survivor from the hillsides of Châteauneuf-sur-Loire, this 17th-century chandelier mill is an exceptional example of Beauceron milling, with a remarkably well-preserved Berton mechanism.

History
Perched high in the Loiret countryside, the Bel-Air windmill in Guilly embodies an often-forgotten page of France's rural heritage: that of the chandelier mills, the pivoting wooden giants that once punctuated the agricultural life of the Beauce region. Listed twice in the Supplementary Inventory of Historic Monuments, it is both a masterpiece of ancient carpentry and a living testimony to the Loire milling industry. What immediately distinguishes the Bel-Air mill is that it belongs to the type of mill on a wooden pivot, known as a "candlestick mill". The entire cage of the building turns around a central post to direct the wings towards the wind - a primitive system in its conception, but one of formidable ingenuity, which the millers of the Beauce region perfected over the centuries. Here, the Berton mechanism fitted to the sixteen-sided motor shaft allows the wings to be opened or closed in full rotation, a rare technical sophistication that can still be seen in the structure. A tour of the Bel-Air mill plunges visitors into the bowels of a machine that is both medieval and modern. The ground floor reveals the sole and its stone dice supporting the entire structure; the middle floor, accessible by an outside staircase, reveals the central pivot and the remains of the sifting mill; finally, the upper level preserves two pairs of millstones - one 210 cm in diameter, the other 150 cm - as well as their lanterns, pinwheels and period gears. A remnant poplar brake blade completes this striking inventory. The surrounding setting, in the Loire Valley at the gateway to the Forêt d'Orléans, adds a poetic dimension to the visit. This gentle bocage, punctuated by open fields where the wind that once made the wings turn has not changed, invites you to take a walk that is as meditative as it is historical. Curious families, lovers of industrial heritage and photographers in search of picturesque silhouettes will all find something to suit them.
Architecture
The Bel-Air mill belongs to the oldest and most widespread type of windmill in Beauce: the wooden pivot mill, commonly known as the "moulin chandelier" or "moulin-tourniole". Unlike stone tower mills, where only the cap turns, here the entire wooden frame cage pivots around a central vertical post - the chandelier - to direct the wings into the wind. The cage rests on a horizontal base that is itself supported by stone blocks, forming a solid foundation anchored in the ground. The building has two functional levels. The first floor, accessible by an outside staircase, houses the central pivot and the remains of the sifting room, where the flour was sifted. The second level, reached by an internal staircase, houses the heart of the mechanical equipment: two pairs of millstones (210 cm and 150 cm in diameter), two truncated cone-shaped lanterns with 12 and 9 spindles respectively, two spindle wheels (60 and 50 teeth) and their large irons. The drive shaft, carved with sixteen facets according to an ancient carpentry tradition, is fitted with the Berton system, an improvement enabling two control crowns to be operated to open or close the wings during rotation - a mechanical refinement characteristic of the 19th century. A remnant poplar brake blade and its lever are still in place, a moving reminder of the last miller to operate the machine in 1914.
