Moulin de Trouguer, Stone windmill in Cléden-Cap-Sizun, France.

Moulin de Trouguer is a tower mill of rough brown and grey granite, its conical roof covered in dark grey shingles. Two sets of wooden sails cross at the top, each with a central beam and many short parallel slats. A small dark window sits above a flat blue door in the tower's front, with a grassy field and low buildings around it.

The mill was built in 1830 and operated regularly until the 1940s, when a storm damaged its structure. The last miller left in 1952, ending the period of active use.

The mill stands on the Trouguer site, and the Marchand family of Trouguer rented it to the miller Jean-Dominique Carval, who abandoned it in 1952. Since its restoration it grinds wheat from the surrounding fields during events, notably the Gouel an Eost harvest festival held every July and the mill heritage days.

The mill is best reached by following the coastal path from Cléden-Cap-Sizun, with parking available near the site. It is advisable to bring weather-resistant clothing, as the location is heavily exposed to coastal wind.

In 2009, its first milling produced 30 kilograms of wheat flour per hour. The mill now grinds grain from neighbouring fields during events such as the Gouel an Eost harvest festival each July and the mill heritage days.
