The Pierres du Diable (Devil's Stones), are listed megaliths dating back from between 2500 and 1500 BC. They are located near the village of Forrières, on the place known as Inzomet (meaning 'at the top'). These stones are the vestiges of a protohistoric megalithic construction.
The stones sit on the place known as Inzomet (which means at the summit). Excavations of the site have revealed that there were initially six dolmens, table-like constructions made out of three stone slabs, which would mean a total of eighteen stones arranged in a circle. Nowadays there are only six left, the others were probably used for the construction of roads etc.
According to local legend, the stones are a load lost by the devil as he was passing, and a treasure is said to be hidden under the biggest stone, treasure that belongs to anyone strong enough to lift the stone...
During the archaeological digs led by A. De Loë that were carried out in 1897, a number of firestones, as well as bone and ceramic fragments were uncovered.
