The Doctor's travels
The Doctor made several visits to Italy.

During this visit he was responsible giving Nero the idea for starting the Great Fire of Rome. (TV: The Romans)

Venice, a city built on marshland by the sea, (TV: The Vampires of Venice) was also of interest to the Doctor. He made several trips to the city in his first, (PROSE: The Empire of Glass) eighth (AUDIO: The Stones of Venice) and eleventh incarnations. (TV: The Vampires of Venice)

Pompeii also attracted the Doctor's attention because of its famed volcanic eruption on 24 August 79. The Seventh (AUDIO: The Fires of Vulcan) and Tenth Doctors were present during the eruption itself. Indeed, the Tenth Doctor and Donna Noble were the proximate cause of the explosion that wiped out the city. (TV: The Fires of Pompeii)

People from Italy
As a populous country with a strong tradition of emigration, Italy had an influence upon the development of the planet Earth that was difficult to quantify. For example, any number of persons of Italian origin passed through the gates at Ellis Island to populate New York City in the 19th and 20th centuries. (TV: Immortal Sins)

Despite the anonymity of the American immigration, a number of specific Italians were known by name.
