Remains of a lavish home and garden occupied by the indulgent Emperor Caligula have been discovered under an office building in central Rome. Italian researchers who excavated the site found a luxury palace with an ornate garden complete with water fountains and an exotic menagerie that housed ostriches, deer and even a bear. Artefacts taken from the site, including jewels, coins, animal bones and a metal brooch belonging to an imperial guard, are set to go on public display. Caligula, the third leader of the Roman Empire, lived a depraved lifestyle, indulging in brazen affairs with wives of his allies and incestuous relationships with his sisters before his murder in AD 41. The remains lie under the offices of Enpam, a doctors' pension institute along Piazza Vittorio Emanuele II - a piazza in south-eastern central Rome.
