The mill uses a horizontal-shaft undershot water wheel, a classic design for high-flow, low-head streams.
The millstones used on-site are carved from local granite, which is historically significant to the regional mill construction.
The restoration project was led by a local association specifically to preserve the industrial heritage of the Cap Sizun peninsula.
The mill is powered by the Keriolet stream, which feeds into the larger Goyen river watershed.
Historically, this mill was central to the local 'bread economy' of Beuzec-Cap-Sizun, serving neighboring rural households.
The site operates as a cultural site during the summer season, often hosting demonstrations of traditional Breton milling techniques.
The Moulin de Keriolet is a restored 18th-century watermill situated in the Goulien valley within the Cap Sizun region of Brittany. It is part of a local heritage initiative that includes a series of watermills powered by the Keriolet stream. The site features a functional undershot water wheel and traditional stone milling equipment used for grinding buckwheat and wheat. Visitors can observe the mechanical transformation of grain into flour during live demonstrations. The surrounding grounds include a riparian ecosystem maintained to protect local biodiversity. It serves as an educational center for traditional Breton agrarian history and renewable energy history.
The wooden bridge crossing the stream provides the best angle for capturing the mill and the water wheel in a single frame.
Wear sturdy, closed-toe footwear suitable for damp, uneven paths along the stream.
Check the official website for scheduled demonstration days, as the inner workings are not always running outside of event periods.
Bring a light jacket, as the valley floor remains significantly cooler and more humid than the cliffside coastal areas.
Do not attempt to touch the rotating machinery or water wheel mechanisms while in operation.
Open seasonally during the summer months; closed throughout the winter period.
