Prima Porta is the 58th zona of Rome, identified by the initials Z. LVIII. The name Prima Porta came from an arch of the aqueduct that brought water to the Villa of Livia, which formed over Via Flaminia a sort of gateway which travellers saw as the first indication of having reached Rome (Piperno).

The Villa of Livia is an ancient Roman villa at Prima Porta, 12 kilometres (7.5 mi) north of Rome, Italy, along the Via Flaminia. It may have been part of Livia Drusilla's dowry that she brought when she married Octavian, her second husband, in 39 BC. However, it may also have been a gift given to her by Octavian upon their betrothal. The ancient sources tell us that Livia returned to this villa following the marriage. It was her sumptuous country residence complementing her house on the Palatine Hill in Rome.
