Odet
The Odet is a river in western France, which runs from Saint-Goazec into the Atlantic Ocean at Bénodet. The name of the town of Bénodet comes from the river; ben means river mouth in Breton.
The river runs past, or through, the towns of Bénodet, Combrit, Plomelin, Quimper, Ergué-Gabéric, Briec-de-l'Odet, Langolen, Coray, Trégourez, Leuhan and Saint-Goazec. It is long and its basin area is.
The river is popular with kayakers.
In 2021, an article published in the Bulletin of the French Prehistoric Society reported that archaeologists had interpreted the Saint-Bélec slab, a 4,000-year-old stone rediscovered in 2014, as a three-dimensional representation of the Odet valley. This would make the Saint-Bélec slab the oldest known map of a territory in the world. According to the authors, the map probably was not used for navigation, but rather to show the political power and territorial extent of a local ruler's domain of the early Bronze Age. Measures of the slab were 2.2 metres long and 1.53 metres wide.
