Commonly called Château des Saptes, the building is in fact, in its functions, a mill. The set was bought at the beginning of the 16th century by the Saptes brothers, drapers. They want to take advantage of its location on a bend in the River Orb to concentrate their activity: preparation of raw wool, washing, fulling, dyeing, weaving, trimming, everything could then be done in the same place.
We find around the castle a set of houses which made it possible to gather around them other related professions. Thus twisters, weavers, re-entryers, masons in charge of building maintenance settled nearby.
