The context uncovered comprised a stretch of an ancient road linking the Castimoeniense to the via Appia, already published, and hydraulic structure situated immediately up hill from the latter. The road was on a south-east/north-west alignment up against a terracing wall built of polygonal blocks sustaining a cut in the bedrock which had probably been created for agricultural purposes. There was a kerb of tufa blocks on the opposite side of the road. In all three of the opened trenches it was possible to examine the stratigraphy of the road bed which was on average 3.13 m wide. In origin the road had been carefully constructed with a small drainage channel running down the middle. A first surface lay on a make-up layer and was overlain by the make-up for the second surface. The latter make-up comprised stones of various sizes and was preserved in only one of the trenches. Characteristic cart tracks confirmed its use. On the basis of what has emerged it is thought that this was a gravel road dated to the mid- Republican period. The drainage structure also finds parallels in analogous contexts of the same period. This was a cistern created in the tufaceous bedrock along the line of a cuniculus. The dry-stone built covering permitted surface waters, collected in the still existing ditch on the up hill side, to be collected in the well. The cuniculus was the main conduit for the regimentation of the water necessary to protect the road. an adequate periodic maintenance of the infrastructure would justify the good state of the road’s preservation and above all, the absence of evidence of dumps of material for the renewal of the road-bed.
