Testaccio started as an industrial area in Roman times where goods arriving by ship on the Tiber were unloaded and processed. Over many centuries, amphorae from imported oils, wines and other goods were discarded there, forming a hill. In the late 19th century, Testaccio regained its industrial role with new infrastructure and housing for workers. While industry is now gone, Testaccio remains a center of life in Rome with sites like its former slaughterhouse housing a museum, and as the home neighborhood of soccer team AS Roma's most dedicated fans.
