Small village of Morbihan, in Brittany region, Guémené-sur-Scorff takes place about seventy kilometers from Vannes, in the district of Pontivy. Born from the dismemberment of the ancient parish of Plousquen, the capital of Pays Pourlet is located about forty kilometers from the Atlantic coast, not far from Locmalo, Langoëlan and Le Croisty.
Guémené exists since the fifth century. We find there a feudal mound around 1050, built by Guégant (or Guegant), son of Périou or Piriou (founder of La Roche-Périou, in Priziac, and grandson of Benedic, count of Cornouaille) and nephew of Alain Canhiart, Count of Cornouaille. Guégant gives his name to the place: Kemenet-Guégant (the fief of Guégant), become by softening and abbreviation Guémené. Originally, Kemenet-Guégant is only a simple chatellenie dependent on La Roche-Périou, in Priziac, and a rear-fief of Porhoët County. The property of the family Guégant fall, in the early twelfth century, in the hands of the family Rohan. Alain Ier became, around 1120, owner of Guémené.
The small town of character is today famous for being the capital of the andouille Guémené, a culinary specialty that has made its reputation throughout the country.
