The full version of the "thermae", or Baths of Agrippa, did not come into use until after the completion of the Aqua Virgo in 19 BCE. This new aqueduct was paid for by Agrippa himself and was one of a series of works connected with Roman water supply and sewers over which Agrippa seems to have had managerial control. The Aqua Virgo is still in use today after almost 2000 years, terminating, and currently supplying the waters to, the Trevi Fountain. These building projects were a few of the many which Agrippa undertook within the Roman "Campus Martius" and across the Empire, constituting aqueducts, fountains, porticoes, baths, roads, a voting precinct, a theatre, a bridge, and a harbour.
