In antiquity, much of the Tiber River trade took place here, and the remains of broken clay vessels (amphorae) were stacked creating the artificial Testaccio hill, which today is a source of much archeological evidence as to the history of ancient everyday Roman life. The rione seal depicts one of these amphorae. In modern times, the area has been a center of activity for butchers. Testaccio was one of Rome’s traditional working class neighbourhoods, but the recent process of gentrification has changed its reputation from hard-at-work to "hipster". The neighborhood is home to several of Rome's culinary highlights. Testaccio's reputation among tourists is expanding.
