An oppidum is a barred spur (semi-natural fortification with an entrance through the plateau, surrounded by deep valleys on 3 sides).

The excavations put in place at the end of the last century allowed the updating of tombs, of bronze coins with the effigy of Epona...

This fortification was probably inhabited 1000 BC and abandoned to the Roman invasion.

Further along the rampart are the spring and the raised stone, sign of the tribe.

This oppidum is accessible for the Bonneval Solitary Trail from the church of Relanges or by the GR7.
