The world's first prototype of the Bollée wind turbine, first documented in Saint-Jean-de-Braye in 1876, this industrial jewel bears witness to the inventive genius of the Bollée family, the great bell founders of the Loire Valley.

History
In the heart of Saint-Jean-de-Braye, in the Loiret region of France, stands a discreet but absolutely exceptional monument: the oldest known example of a Bollée wind turbine, listed as a Historic Monument since 1993. At a time when renewable energies are being debated, this 19th-century prototype is an elegant reminder that human genius was already trying to tame the wind long before our late industrial era. What makes this wind turbine unique in the world is its status as an original piece in the genealogy of a major French invention. Designed even before the official patent was filed in 1885, it has some fascinating archaic features: the absence of the flared rim that would make Bollée wind turbines commercially famous, and a mechanism with two pistons driven directly by a horizontal shaft, whereas later models would have three. These calculated imperfections are precisely what make it an irreplaceable technical document. The wind turbine had an eminently practical purpose: to supply the family home and the Bollée bell foundry, one of the most illustrious in France, with running water. It probably replaced a pre-existing waterwheel, making its history part of a long tradition of water collection. To see this structure is to plunge into the mental workshop of Ernest Bollée, the inventor, and his son Auguste, who perfected his father's work. A visit to this intimate monument is just as much for those with a passion for industrial history and technical archaeology as it is for those with a curious interest in the great names of French engineering. In an area where the heritage of the Bollée family still resonates - bell founders, pioneering car manufacturers - the wind turbine takes on an almost dynastic dimension, a tangible symbol of a line of builders who shaped their era. The setting of Saint-Jean-de-Braye, a town in the Orléans conurbation bordered by the Loire, adds a touch of Loire charm to the visit. This fertile land, bathed in the distinctive light of the Loire Valley, forms a natural backdrop that contrasts pleasantly with the sober metal and functional design of this machine for capturing the wind.
Architecture
The Bollée wind turbine at Saint-Jean-de-Braye belongs to the first generation of horizontal axis wind turbines designed for pumping water. Its sober, functional silhouette is that of a machine designed by engineer-craftsmen rather than architects, giving it a raw, authentic charm characteristic of the industrial genius of the 19th century. Structurally, the device consists of an impeller mounted high up to capture the wind, connected by a horizontal shaft to a two-piston pump mechanism installed near the well. The absence of the flared rim - an innovation patented in 1885 to channel and amplify the flow of air towards the vanes - immediately distinguished this prototype from later commercial models. The materials used were those of nineteenth-century foundries and forges: cast iron, wrought iron and steel for the mechanical parts, and wood for certain structural elements. The whole reflects the expertise of the Bollée foundry, which specialised in metalworking. The layout was designed to meet strict practical requirements, including positioning close to the well to be supplied and in an open area to maximise wind resistance. This prototype illustrates the transition from traditional animal- or human-drawn pumping systems - the noria that it replaced - to the autonomous machines that would mark the modernisation of French rural and industrial farms in the last quarter of the 19th century.
