The Villa of Domitian, known as Albanum Domitiani or Albanum Caesari in Latin, was a vast and sumptuous Roman villa or palace built by emperor Domitian. It was situated 20 km (12 mi) from Rome, high in the Alban Hills where summer temperatures are more comfortable. It faced west overlooking the sea and Ostia. To travellers on the via Appia it would have made an impressive sight.

Alba Longa was an ancient Latin city in Central Italy in the vicinity of Lake Albano in the Alban Hills. The ancient Romans believed it to be the founder and head of the Latin League, before it was destroyed by the Roman Kingdom around the middle of the 7th century BC and its inhabitants were forced to settle in Rome. In legend, Romulus and Remus, founders of Rome, had come from the royal dynasty of Alba Longa, which in Virgil's Aeneid had been the bloodline of Aeneas, a son of Venus.
