Major funds would be required to excavate the Oppio hill in Rome.
A "new Pompeii" could lie hidden deep beneath Rome's Colle Oppio however it would take "several millions" of euro to excavate it, according to Eleonora Ronchetti of the capital's culture superintendency.
Ronchetti made her remarks during a meeting with the city's culture and environment committees to discuss a playground project on the site which is best known as the home of Emperor Nero's Domus Aurea.
Ronchetti said that the entire area of the hill, which overlooks the Colosseum, could contain the remains of the Baths of Titus. The bath complex, which dates to 80 AD, was excavated partially on the hill in 1998-1999 before being reburied for safety reasons.
