In the middle of the 19th century, Kermoisan had two bread ovens and about thirty buildings, farms grouped around courtyards, but also small dwellings in rows. The openings, with basket-handle and semicircular doors still in place, indicate that the hamlet was already inhabited during the 17th century. In the 20th century, buildings grew up along the roads leading to Quistinic and Poul Fetan.
