In the locality of Cimitero circa 280 m north-west of Cales thirty-one test pits and sixteen trenches were excavated. Evidence indicated that the north-eastern sector of the area was used as a necropolis probably between the 4th and beginning of the 3rd century B.C., with burials on a north-east/south-west alignment. The chronology is mainly based on the tomb types as most of them had been robbed during illegal excavations. Three tombs were of the “a cassa” type in tufa, two had tympanum ends and sloped covering, a third probably had a flat covering. Together with these a single earth grave was also discovered. Investigations in the south-east of the area revealed evidence of the re-arrangement of the water supply system immediately north of ancient Cales. The features identified belong to two different phases. An artificial cut in the tufa bed-rock, perhaps used for rainwater and hill-wash collection, linked to a network of channels on the surface dates to the first phase. Water collection through this system must have been part of an overall territorial plan and must have allowed the maximum exploitation of agricultural land. Although some doubts remain, this infrastructure probably dated to the setting up of the Latin colony in 334 B.C. The entire water supply system, although partially obliterated, was reused during the course of the second half of the 3rd century B.C. following the construction of a well and a shallow tank lined with _opus signinum_. The well collected rainwater and must also have collected the waters running down from uphill via a circular aperture in the tufa bed-rock. The water fed into the tank, which had a portico on its western side, some traces of which are still visible. Some doubts remain regarding the function of this complex, which may have been a villa rustica.
