A 16th-century cave mill in Bourgueil, a legacy of the Benedictine monks and a testament to seven centuries of milling in Touraine. Its patented Berton wings and masonry mound make it a rare part of the Loire's wind energy heritage.

History
Standing on its massive circular mound at the gateway to Bourgueil, the Moulin Bleu embodies a form of rural intelligence that the centuries have not erased. A Historic Monument since 1974, this cave mill is part of a milling tradition that has been rooted in the Tourangeau region since the Middle Ages, carried on by the Benedictine monks of the powerful local abbey long before the large seigneurial farms made it their production tool. What sets the Moulin Bleu apart from most of its peers is the permanence of its architectural silhouette. Unlike wooden tower mills or fragile pivot mills, this hollow mill rests on a sturdy masonry base, crowned by a dome and a cone, giving the whole structure an almost fortified appearance. From a distance, its compact mass, set on a promontory of stone and rock, is more reminiscent of a vineyard lookout than the slender silhouette of a mill on the plain. The visit reveals several superimposed layers of time. First you discover the medieval skeleton - the stone barrel vault, the solid masonry - then the large wings known as "Berton", a system patented in 1845, reassembled and refurbished in 1933 after the ravages of the tornado of 1875. Inside, the framework that once held the millstones in place bears witness to the mechanical genius of the milling craftsmen. A concrete slab poured by the German occupiers during the Second World War is a stark reminder of the military uses to which this panoramic terrace was requisitioned. The setting of Bourgueil adds to the interest of the site. In the heart of the UNESCO World Heritage Loire Valley, the mill is set in a landscape of vines and tufa rock, where history seems to surface at every turn of the road. A monument both humble and eloquent, it silently recounts the economy, conflicts and skills of a region shaped by its waters and winds.
Architecture
The Moulin Bleu belongs to the family of cavier mills, characterised by a fixed base of solid masonry on which only the upper part - the cap - bearing the wings and mechanism pivots. This design, which is heavier than that of fully rotating pivot mills, offers superior stability and durability, particularly suited to the regions exposed to the irregular winds of the Loire Valley. The base of the mill is an imposing circular mound of masonry and rockwork, typical of the troglodytic constructions and tufarelle traditions of the Bourgueillois region. Inside this mass is a stone barrel vault, a functional space that housed the lower mechanisms and storage exits. Above, the cylindrical masonry body is crowned by an open dome on which rests a cone - the calotte - made of ashlar, forming the turning part of the mill. Inside the main body, the structural frame - a large assembly of beams and squared timbers - formed the mechanical framework holding the drive shaft and the axis of the millstones. The wings, restored in 1933 according to the model patented by Berton in 1845, are of the hinged flap type, allowing fine modulation of the surface area exposed to the wind. This system, sophisticated for its time, represented a significant advance on the full-canvas wings of earlier mills. The 1933 reconstruction respected the original proportions and technology, making the Moulin Bleu a coherent testament to 19th-century wind milling. Only the concrete slab poured over the vault by the German army stands in stark contrast to the homogeneity of the rest of the building.
