Small town of Morbihan, in the Brittany region, Guémené-sur-Scorff takes place about seventy kilometers from Vannes, in the arrondissement of Pontivy. Born from the dismemberment of the former primitive parish of Plousquen, the capital of the Pays Pourlet is located about forty kilometers from the Atlantic coast, not far from Locmalo, Langoëlan and Le Croisty.
Guémené has existed since the 5th century. There is a feudal mound around 1050, built by Guégant (or Guegant), son of Périou or Piriou (founder of Roche-Périou, in Priziac, and grandson of Benedic, count of Cornouaille) and nephew of Alain Canhiart, count of Cornouaille. Guégant gives its name to the place: Kemenet-Guégant (the stronghold of Guégant), which has become by softening and abbreviation Guémené. Originally, Kemenet-Guégant was only a simple châtellenie dependent on La Roche-Périou, in Priziac, and a back-fief of the county of Porhoët. At the beginning of the 12th century, the property of the Guégant family fell into the hands of the Rohan family. Alain I becomes, around 1120, owner of Guémené.
But the architectural heritage is not the municipality's only asset. Indeed, one cannot evoke Guémené without immediately thinking of its famous andouille and its inexhaustible producers on the artisanal manufacture of this specialty which makes the pride of Guémenois. This famous andouille, recommended by the greatest chefs of French gastronomy, gives rise to a big party every year at the end of August.
