Landerneau

It lies at the mouth of the Elorn River which divides the Breton provinces of Cornouaille and Léon, 22 km (14 mi) east of Brest. The name is from Lan Terneo and can mean "(religious) enclosure of St Ténénan (Welsh: Tyrnog)": allegedly a Welshman who also had llans in the Vale of Clwyd in North Wales and in Somerset, and who moved to Brittany in the 7th century. Lann means a religious sacred place. The town has been founded by Saint Arnoc, some times called Ternoc and confusion can occur with Saint Ténénan. Some sources point Saint Arnoc and Saint Ténénan as the same person.

It was an important centre of the flax and linen industries in the 16th and 17th centuries. Landerneau is also the hometown of Édouard Leclerc, a businessman and entrepreneur who founded the French supermarket chain E.Leclerc in 1948. The town is actually the heart of the agricultural market in northwest Brittany with several agribusiness companies headquarters located in the town.

The town is also known for its moon, La Lune de Landerneau (the Moon of Landerneau). This nickname is supposed from a noble visiting Versailles court and was not impressed by the luxury of the Château de Versailles.
