He also mentioned a large number of archaeological findings of that period, which occurred very close the megalithic walls and that now have been lost.According to the common opinion, Altamura was said to be placed on top of highest part of an ancient wall, which still exists, and it is believed to be older than the time the city was refounded by the emperor Frederick II.
This ancient wall, made of large square stones, is about three miles long; starting from the top and spreading along the base of the hill, facing towards the North.
Up to the present time, such a wall preserves the ancient remains of three of its gates, and it embraces some small roads, and landed wells.
Along the foot outside this wall, and in its vicinity, ancient sepulchres, with human bones, of both precious and low-metal medals, Greek and Roman, are found from time to time under the ground; household tools, perpetual lamps, with asbestos wicks: basins, lacrimal urns [..].
From similar findings, it is inferred that such an old wall belonged to a sacked city.Inside Rocca map P/33, commissioned by Angelo Rocca and stored inside Angelica Library, Rome, some memorial stones can be seen on the megalithic walls.
