Area archeologica di via Rinarolo a Tortona

In via Rinarolo, on the northern edges at the height of the castle, recent excavations have brought to light a consistent run of walling with building techniques (substrate terracing, bagged working, double-walled square blocks) and angling similar to that at via alle Fonti, but with a movement towards the east of around 120 metres; on the eastern side can be seen thick buttresses belonging to the same period of construction. It is not yet possible to give a precise interpretation of the remains; if the method of wall construction could make one think of successive enlargement with respect to the fortification from via alle Fonti, the different positioning and the presence of buttresses on the eastern side of the construction recall terracing in opus vittatum, well-recorded in central-southern Italy from the 3rd to 2nd Cent BC
