An open-air pit
The right-angled cuts in the banks of rocks represent the oldest human intervention known in the area. In fact, probably until the Late Punic age (IV-III B.C.) a quarry to extract limestone rocks from the open pit was implanted. Following this, on the occasion of building a sanctuary in this urban area (area 1), the cuts in the rocks were filled-in with calcareous powder compressed in a way to obtain a uniform, even floor. The material of the pit was furthermore used in the construction of a wall to contain the thesaurus of which 3 rows of isodomatic structure remain (a masonry technique which involves the use of square blocks arranged in a regular line) with a swell in elevation.
