What Travellers Say
Reviews Summary
Visitors find the Cryptoporticus Nero to be a fascinating glimpse into the hidden infrastructure of ancient Roman palaces, enhanced by modern projections and music. While it's a functional entry point to the House of Livia, its historical significance and unique presentation make it a memorable stop for those with the correct 'Super Sites' ticket.
"Running beneath the Farnese Gardens on the Palatine, the so-called Neronian cryptoporticus is a long, semi-subterranean corridor that once formed part of the service spine of the Domus Tiberiana. Built in the mid-first century CE, it stretches for over a hundred metres along the terrace, lit by small high openings and still preserving patches of mosaic floor and painted plaster. The passage allowed movement between palace sectors in shade and relative secrecy, linking residential areas, service rooms and later the Flavian buildings. Ancient accounts place Caligula’s assassination in a cryptoporticus under the imperial palace, a tradition often associated with corridors like this. Today it functions as both support structure and museum route, revealing the hidden engineering of the hill."

"As of May 2025, the Neronian Cryptoporticus is used as the entry to the House of Livia. Projections are made on the walls of the Cryptoporticus with classical music. One needs to have the ticket to the Roman Forum that includes "Super Sites"."

"These days it's an unadorned tunnel leading to Palatine palaces. According to Suetonius, Caligula was probably assassinated here;also killed here at the same time were his wife, Caesonia, and their infant daughter, Julia Drusilla."
