The volume presents the archaeological investigation carried out in Palazzo Vecchio, which made it possible to bring to light part of the Roman theater on which stratifications dating back to the modern era were deposited. The data that emerged during the survey made it possible to show how the theater, built on the occasion of the foundation of Florentia, changed its intended use in late antiquity. Subsequently, the monument was transformed into a sort of container into which consistent dark layers were poured. Between the XNUMXth century and the XNUMXth century, the area of the theater was recovered with the construction of buildings, towers, leveling and terracing. Later the ruins of the structure, which still kept its bulk intact, became part of that urban space managed by the Uberti family, which made it a real urban enclave. The volume contains a conspicuous catalog of the rich late medieval ceramic finds, found during the excavation, and which then return to talk about a complex economy resulting from a rapidly growing society.
