In 2013, the research undertaken by the International Institute of Ligurian Studies concentrated on the western sector of the area of the north walls, occupied by the Porta Nord gate and a late antique cemetery.

At the Porta Nord, the investigations revealed an ashy layer (US 3097) below the ground surface relating to the necropolis (US 3070) and a series of layers with a clay matrix (US 3090, 3095). The ashy layers were evidence of hearths or production areas, similar to those identified in the adjacent Cardo A during the 2011 excavations.

The continuation of excavations in the late antique cemetery in area 4000 revealed a series of tombs of various types: T 12/311 (in amphora), T 17/316 (“a cappuccina” with a single-sloped covering abutting a wall), T18/317 (tile coffin), situated up against the north face of the town wall. The excavation confirmed the chronology of the two phases of use known to date (phase 1: mid-second half of the 5th century A.D.); phase 2: end of the 5th-6th century A.D.). There was an interesting change in the position of the body in T17, a young, perfectly preserved individual, orientated west-east, with the head to the west, the only example identified among the 40 burials excavated to date.

Lastly, a stretch of a small road was uncovered to the south of room ‘O’. Carefully paved with gravel and bordered by two rows of cobbles, it ran on a diagonal with respect to the other structures of the villa. It was obliterated during the villa’s final occupation phase.
