Having survived five centuries of milling, the Jau mill reveals its majestic 5.60-metre undershot wheel and its rare, intact miller’s equipment, watched over by a statuette of Saint Catherine nestled in the stone.
History
In the heart of the Anjou countryside, on the quiet banks of a wooded stream, the Moulin de Jau is one of the most complete examples of the art of milling in Maine-et-Loire. Listed as a Historic Monument in 1984, it is as fascinating for the diversity of its past functions as it is for the remarkable integrity of its mechanisms, which have been painstakingly restored to their original condition. Here, the history of rural industry can be read in every beam, every blade and every millstone. What makes the Moulin de Jau truly unique is its multi-functional history: over the centuries, it has ground grain, fulled cloth, crushed oak bark for tanning, before returning to its original vocation as a cereal mill. This ability to adapt is a testament to the ingenuity of local millers and the economic vitality of the Anjou bocage. The bark shed still standing in the courtyard is a rare vestige of the pre-industrial tanning industry. The tour is structured around the gradual discovery of a living mechanical organism. On the ground floor, the pit and its angle gear reveal the sophistication of the hydraulic transmission system. Upstairs, the millstones take pride of place in the subdued light, evoking the age-old gestures of the millers. The highlight of the visit is the lower wheel, sheltered under a gabled lean-to overlooking the stream: its eight arms and forty-eight straight vanes have been turning again since it was restored in 1994, offering a mechanical spectacle of rare authenticity. The bucolic setting adds to the enchantment: the running water, the changing reflections on the wheel and the stone niche housing the statuette of Saint Catherine, patron saint of millers, give the place an atmosphere that is both peaceful and steeped in history. The hammer used to dress the millstones, on display in the open air, is a reminder that milling was a physical, demanding and precise profession. An hour spent here is enough to understand just how central the mill was to French village life.
Architecture
The architecture of the Jau mill is simple and functional, typical of the rural hydraulic mills of the Anjou bocage in the 19th century. The main body of the building is square in plan, covered by a pavilion roof with four slopes, giving it a compact, balanced silhouette that is firmly rooted in the valley landscape. The materials used - local stone and timber - are in keeping with the building traditions of the region, with an economy of means that does not exclude a certain care in the matching. The interior layout follows a rigorous mechanical logic: the ground floor houses the hydraulic pit and its angle gear, a mechanical device that transmits the rotational movement of the horizontal axis of the wheel to the vertical axis that drives the millstones. The millstones are located on the upper floor, a classic configuration that facilitates grain feeding and flour collection. This functional superposition is one of the most distinctive features of traditional mill architecture. The most spectacular architectural feature is the gabled lean-to attached to the north side of the main building. Spanning part of the watercourse, this light structure houses the wheel below, known as the straight-bladed wheel: with a diameter of 5.60 metres and a width of 1.50 metres, it has eight arms and forty-eight blades, a configuration that optimises the harnessing of hydraulic energy through the thrust effect. Outside, a niche in the masonry houses a statuette of Saint Catherine, patron saint of millers, accompanied by a hammer for dressing the millstones and a millstone standing vertically: a veritable secular altar dedicated to the trade.
