Archaeological investigations undertaken in 1994 and 1999 during the laying of sewer pipes in the town of Vaste revealed an important sacred complex whose main phases dated to between the end of the 4th and first half of the 3rd centuries B.C. The complex was divided by stone-block walls into areas interpreted as enclosures, housing hearths and cooking surfaces.

Three underground rock-cut chambers for offerings were identified nearby. The centre of the cult site seemed to be a larger cavity, delimited on the ground above by an enclosure of stone blocks. It was possible to go down into the cavity and carryout rituals at another crevice, at the base of which was a limestone slab with a central hole, bedded in the clay terrain. In 1994, an altar of stone blocks was found to the south-east.

The cult site was closed to the west by a substantial wall with foundations of large stones that already marked a boundary in the archaic period. Some materials dating to between the end of the 8th and first half of the 7th centuries B.C. may date a first cult use of the area.

In the Roman period, this part of the town underwent radical transformation: a cooking stand was installed inside one of the enclosures and numerous middens were present across the entire area.
Rubbish-dumps probably relating to the nearby palazzo Baronale and datable to between the 13th and 17th centuries, were also identified.
