Note 4 — Chapter VII · Camps, Fortifications, Vitrified Forts; Santorin; The Towns upon the Hill of Hissarlik.
N. D'Anvers translation
The camp of Pont-de-Bonn in the commune of Modave (Namur) very much resembles in its arrangement that of Hastedon.4 A mound stands out upon the plain protected on the north and west by rocks difficult of access and connected with the main plateau by a very narrow tongue of land. Outside we can make out regular trenches parallel with each other, and connected by a wall of masonry, at the foot of which wall were picked up a good many iron nails. Inside the enceinte itself worked flints were associated with Roman coins. Are not these proofs in the first place of a long Neolithic occupation, then of the residence of Gallic Romans, and yet later of even more modern people of whom the masonry walls and iron nails are relics?
