The staging completes the exhibition of the museum's lapidary collections, already partially housed in the arms of the two cloisters. The new lapidary is located in a large enclosed garden, on the edge of the museum area, sheltered by a steel and translucent polycarbonate roof built in 2015 and attached to the new café building.
The curators have defined a chronological exhibition itinerary, from the pre-Roman age to the 18th century, in which a small selection of stone finds recount the salient episodes of the city's history.
The finds are exhibited on independent supports and bases in painted steel, on large cocciopesto panels fixed to the structure of the portico, or inside a counter-wall leaning against the nineteenth-century building of the laboratories, shaped so as to incorporate the external plant units, and composed of steel profiles and lamato rosy cocciopesto panels.
The design of the supports is coordinated with those of the two existing lapidaries, as well as their anthracite color; the exceptions are the panels covered in cocciopesto, which characterize the new lapidary. The exhibition is completed by the reconstructions of paving stones, aqueducts and Roman funerary enclosures, distributed in the garden.
The lighting consists of luminous lines parallel to the structure of the roof and point projectors, for accent lighting of the most significant finds.
