The Moulin Martin, which dates from the 18th century, is located in Javerlhac-et-la-Chapelle-Saint-Robert. It is a working water mill for walnut oil. It is equipped with a moving paddle wheel. It is possible to visit it by appointment.
This very beautiful little castle in the Périgord Vert is unfortunately private and impossible to visit but very charming from the outside and really worth the detour.
The current castle of Montbron (or Old Castle) was built during the 15th century, around 1480, shortly after the Hundred Years War left behind many destructions.
