The necropolis F was used for several centuries. Although the most frequented phase is Golasecca I A1 (c. 935 - 800 BC), there are in fact more recent isolated tombs up to G. II B (525-480 BC) and the Roman rooster era. A new necropolis was discovered accidentally, again by Walter Baronchelli in 1976. During excavation works around hundred meters south of the burial ground F, numerous fragments of clay belonging to Iron Age tombs were unearthed. Two burials with relatively well-preserved ceramic could be recovered. In the tombs they found urns, vases and bowls that dated back to Golasecca culture. No further excavations were carried out in the area. The finds were delivered to the municipality and then deposited in the Museum of Antiquities of Turin. The Franciscan convent on Monte Mesma  Parallel to the research in the necropolis areas, Giulio Decio also conducted excavation tests on the slopes of Mount Mesma, under the Franciscan monastery where brick fragments from the Roman era had been found. The research led to the identification, in various points, of fragments of protohistoric domestic pottery in a secondary position, bronze fibulae and remains of clay fictile from the Roman period. These discoveries led the Decio to hypothesize the presence of a built-up area on the well-stocked summit of Mount Mesma, from which the surrounding area is easily dominated. An indirect confirmation of the strategic value of the place, centuries later, is given by the construction in the Middle Ages of a castle, probably in 1200, by the Municipality of Novara . The present Franciscan monastery was later built on the ruins of this. The necropolises discovered in Lortallo were located along the main access road to the town, according to a use widely attested in the early Iron Age . The village on Mesma was the most important, but probably not the only inhabited center. According to the use of the golasecchiano world, smaller nuclei, linked to the main by clanic constraints, had to rise on the surrounding hills. Coeval ceramic remains were in fact recovered in Lortallo and on the Buccione hill. The Roman period is less documented in Ameno than the Iron Age is. At Lortallo and on the Mesma, there are lots of tourists, but since what they've found relating to the period are isolated and accidentally found, it is not currently possible to reconstruct the general picture of the settlement.
