Langonnet is a commune in the Morbihan department of Brittany in north-western France.[2]
Langonnet is in north-west of Cornouaille, in Lower Brittany. It is one of the few Cornouaille parishes to be located in the present-day Morbihan department. Thus, the main language was Breton until the advent of intensive farming after the Second World War, at which point the population, previously bilingual, switched to French.
The parish comprises two main settlements:
In the south-east is the former Langonnet Abbey (Abbaye Notre-Dame de Langonnet).
The highest point of the parish is the calotte Saint Joseph, a round hill whose top is 292 meters above sea level. It offers a good view of the surrounding area, most of the parish being at 190-meter level.
Langonnet is bordered by Plouray and Priziac to the east, Le Faouët to the south, Le Saint and Gourin to the west and Tréogan, Plévin, Paule and Glomel to the north.
The commune's name is written "Langoned" in modern Breton but has been spelled in various ways through the years due to various attempts to transcribe the Breton phonetic system into the Latin alphabet:
The name is said to come from "Lann-Conet", the monastery ("lan" in Breton; compare Welsh "llan", as in Llanelli) of Conet[3] (or Conoit, Konoed, Kon(n)ed, Konoid = Cynwyd, Kynwyd or Kynyd in Welsh), a Welsh saint who was active in Brittany.
Inhabitants of Langonnet are called Langonnetais in French and Langonediz in Breton. Langonnet's population peaked at 4,848 in 1931 and declined to 1,708 in 2020. This represents a 65% decrease from the peak census figure.
The municipality launched a linguistic plan through Ya d'ar brezhoneg on 27 January 2005.
