In the territory of Gricignano stretches of Roman canals on a north-south alignment were found. Of Imperial date, they were used in agriculture, and were perhaps connected to a structure in _opus caementicium_, preserved at foundation level, to the sides of which there was a small necropolis (3rd century A.D. The tombs were “a cappuccino”, earth graves and there was one child burial inside an African II type amphora. The underlying prehistoric levels revealed the presence of several wells linked to a small channel. The sparse material recovered from the obliteration levels of these two structures indicate that they were abandoned between the end of the late Bronze Age and the early Iron Age. In the immediately adjacent zone (circa 2160 m2) investigation revealed an area to the north used for agriculture purposes. This was characterised by the presence of wells, small channels and post holes constituting palisades and defences for the wells (late bronze and early Iron Age). The zone to the south was occupied by a village of which two huts have been found to date. The first was rectangular with an apse in the short northern side, the second was also rectangular but larger and both short sides were apsed, its roof was supported by a central row of posts. Other wells were excavated to the immediate north of the structures, from which fragments of impasto pottery were recovered. After their abandonment a small early Iron Age necropolis was built over the huts. Two of the three tombs found held cremations and tomb groups comprising miniature vases. The third burial, an inhumation, was cut by a later channel from whose fill two bronze _fibulae_ from the tomb group were recovered, one with a serpentine bow, the other with a simple bow and both with incised decoration. Below the eruptive material from Agnano Monte Spina fragments of painted pottery of the Serra d’Alto type, obsidian blades and flint tools (Neolithic period) were found.
