Today we continue the investigation around the tower. To the north, we continued to remove the layer of earth US 21, putting ever more in light the collapse of US 22, particularly in the angle formed by the walls US 33 and 34.
To the southwest, close to the wall US 13, was drawn to the wall US 38, formed with stones of small - and medium-sized fragments of tiles for reuse. It is still not perfectly clear what the connection with the wall of the tower, even if the wall US 38 seems to have been cut by it.
Also, almost behind the walls US 4, it was discovered another piece of masonry (US 40) composed of medium to large sized stones linked by the same type of mortar (yellow sandy matrix) that characterizes even the walls of tower.
