A few metres from the Torre dei Gualtieri, a Roman villa of the 1st–2nd century AD, discovered in 2010 and now open to the public. The floors have black-and-white mosaics; one of them, on the threshold, depicts a prawn. The 2020 excavations also turned up the plant for producing garum, the fermented fish sauce of Roman antiquity — a sort of anchovy colatura avant la lettre, made with prawns and deep-water fish. One part can be visited inside the former Sciarra school building; another part can be seen from outside, in Piazza Sacconi, through transparent display cases.
