Châteauneuf-du-Faou (Breton: Kastell-Nevez-ar-Faou, before 1958: Châteauneuf)[3] is a commune in the Finistère department of Brittany in north-western France.

A large number of tumuli discovered near the sides of the road from Châteaulin to Carhaix testify to the density of the prehistoric population.

[8] During its history Châteauneuf-du-Faou was given different names in Latin and French: Castrum Novum, a new fortress, was built by the lords of Faou.

The story is told that a Huguenot soldier seized a holy ciborium and threw it onto the ground.

Looked on as miraculous, the find was celebrated by the building of the chapel of Notre-Dame-des-Portes, a very popular place for pilgrimage throughout Brittany.

He was a mystic artist and a founder of the group who called themselves Les Nabis, after the Hebrew word for prophets.

Randolph Caldecott visited Châteauneuf-du-Faou in 1874 and made sketches of a Pardon which took place in the rain.
