Moulin de Perros owes its name to the mill that once stood to the right of the current houses below, along the Brûlé stream, better known as the Brandifrout. You'll cross this little river several times during your walk. Rising north of Bubry before flowing into the Blavet at the village of Brandifrout, its main tributaries are the Fontaine Saint-Hervé, Locqueltas and Coëtano streams.
Although modest in size, at various times the Brandifrout has supplied water to no fewer than eight mills over its 14 km length: the Rousse mill, the Perros mill, the Brétinio mill, the Coëdiquel mill, the Duc mill, the two Brûlé mills in Bubry, and the Villeneuve Jacquelot mill in Quistinic.The Brûlé mills are among some of the few flour mills still in operation.
The second mill on this stream, the Perosse grain mill, was part of the estate of the same name, 800 metres to the northwest. Built in the 17th century by the de Penros family, who took part in the Men-at-Arms show in Vannes in 1464, the manor house and its outbuildings were once owned by Marshal Franchet d'Espérey. On leaving the Moulin de Perros, you will see a roadside cross dating from 1807. Unadorned in Latinate form, it sits on a square base accessible by steps.
