Excavations in the area of the north wall of the town of Albintimilium began at the end of the 1980s and were resumed in 2002. A substantial part of the curtain wall delimiting the ancient centre to the north, close to the slopes of the Collasgarba, has been uncovered.

Adjacent to the north side of the wall, in the western sector of the excavation, a small late Roman (5th-6th century A.D.) necropolis came to light. The tombs were of various types (in amphora, “a cappuccina”, masonry built), roughly orientated east-west and each presenting at least two distinct phases of deposition. To the south of the curtain wall, in the eastern part of the excavation, the terminal part of a Roman cardo was uncovered, in a sector characterised by the presence of a series of rubbish pits filled with diverse materials (pottery, glass, bronze etc.) of late antique date. During the 2003 campaign a small town gate was identified, which can be put into relation with the nearby castellum aquae and a probable link to the Val Nerva lying behind, site of agricultural estates and suburban agglomerates.

The 2009 research concentrated on the eastern part of the excavation area, where the levels relating to the construction of the walls are being investigated. The walls were built in the 1st century B.C. directly on the hill slopes, close to the remains of the pre-Roman settlement occupied by the Liguri Intemeli mentioned by the ancient literary sources.
