The three story flour mill, built with pebble stones, belongs to Philippe Manoël de Nogaret from the castle of Ayres in 1841, according to the cadastre. Located on the banks of the Jonte at a place called the Plaine, it is fed by a canal deriving water from the Brèze. A 5-horsepower hydraulic motor is installed in 1855. The carding and weaving factory Vincent is situated next to the mill in the same year (1855). According to oral tradition, Jean-Antoine Veygalier who lives in a building located across the road along the Brèze operates the mill. In 1866, with the closing of the textile industry, the mill only works as a flour factory until about 1940. Currently, the mill is restored into a house. In the 20th century, the building served as veterinary infirmary, then stables and shed. The entire mill Montblanc occupies 438 m2.
