The Hénan tidal mill is located on the banks of the Aven, along the GR®34. It is a symbol of Névez’ heritage which has been restored and can produce flour. There are accounts that mention tide mills as early as the 15th century. The Hénan mill uses the ebb and flow of the river Aven to activate its two large wheels and drive the internal mechanisms. It has a quadrangular roof, the shape of which suggests that it was originally made of thatch.
This historic monument is worth a few minutes’ stop, both for its originality and for the beauty of the site. At low tide, the Aven retreats and reveals magnificent reliefs of mud and some beached wooden structures.
