Early history[edit]

See also: Vatican Hill

The Vatican obelisk was originally taken from Egypt byCaligula.

The name "Vatican" was already in use in the time of the Roman Republic for a marshy area on the west bank of the Tiber across from the city of Rome. Under the Roman Empire, many villas were constructed there, afterAgrippina the Elder (14 BC – 18 October AD 33) drained the area and laid out her gardens in the early 1st century AD. In AD 40, her son, Emperor Caligula (31 August AD 12–24 January AD 41; r. 37–41) built in her gardens a circus for charioteers (AD 40) that was later completed by Nero, the Circus Gaii et Neronis,^[26] usually called, simply, the Circus of Nero.^[27]
