As part of the archaeological investigations prescribed by the relevant superintendency, traces of ancient quarrying activity were identified. The evidence comprised a series of cuts in the tufaceous bedrock at right angles to each other, which formed a rectangle with sharp corners and straight sides on a north-north-west/south-south-east alignment. The profile of the walls was straight and there was a clean break between the wall surface and the upper edge. Traces of the tool used were visible along the exposed walls and the clefts left by the removal of blocks of stone.
The grooves incised in the rock in an almost geometric fashion guaranteed the extraction of blocks having the form and dimensions the closest possible to those that were usable. Two quarry marks were also present on the inside and outside of the same front.

The quarry seemed to have exploited a tufaceous outcrop in correspondence with the edge of a natural hollow.
Cultivations would have exposed the slope below to hill wash were it not for the presence of a drainage channel which, a little lower down, collected the surface water and channelled it towards the valley bottom.
The scarce fill of the quarry cuts did not, as is often the case, seem to contain any anthropogenic evidence. However, the drainage channel presented unequivocal evidence of its abandonment in antiquity.
The channel was on a south-east/north-west alignment with a 3.1% gradient. It was 1.20 m wide and had straight edges, the walls were straight, sloping towards the bottom, the break between the walls and upper edge was imperceptible. Several brick fragments that were certainly ancient, but not of any significance for dating, were found in the two trenches dug into the fill. In the uphill trench a flat flint flake was found on one of the surfaces.

This type of technical expedient was frequently used after the 3rd century B.C. when occupation of the territory was strictly linked to the organisation of villas and farms with the related medium sized estates. This type of drainage is mentioned by Columella (r.r., II, 2, 9-11) with reference to the agricultural exploitation of wet lands. From the end of the 1st century A.D. and during the following century with the affirmation of the latifundia, these expedients gradually disappeared.
