The Colosseum, formerly called the Flavian Amphitheatre, was equipped in times after its original construction with impressive underground passages, in which the 'backstage' fights took place The underground passages were built by Domitian, through a system of tunnels and corridors. The dungeons have been remodelled and renovated several times, and today can only be visited with a guide. Tourists have only been allowed to visit the underground passages of the Colosseum since 2010, and it is one of the most popular visits at the moment. The booking for the full underground experience is therefore strongly recommended, to avoid spending the day in the ticket office.

The Roman Forum is located right in front of the Colosseum and is only a few steps away. It would be a real shame to miss out on a visit to the Roman Forum for not having booked an entrance ticket in advance! Inside the forum you will find yourself inside a real Roman city, with incredibly well-preserved ruins of streets, palaces and squares. You will see the Arch of Titus, the Arch of Severinus the Seventh, some ancient Roman temples such as the Temple of Antoninus and Faustina.

The Palatine is the ancient hill on which the earliest nucleus of the city of Rome stood. Here, in fact, the remains were found of the ancient Iron Age settlements. Between the 2nd and 1st centuries B.C., the Palatine became the residential quarter of the Roman aristocracy, with incredible aristocratic residences, elegant and characterised by paintings, decorations, and floors of extraordinary value. The Palatine was the home of Augustus and later the seat of the imperial palaces, becoming the heart of the city. Here stood the Domus Aurea, the residence of Emperor Nero. The Domus Aurea was an impressive residential complex with sumptuous decorations, marble, gold and precious stone cladding, remodelled and partly destroyed by the successors of Augustus.

A few steps from the Colosseum, between the Circus Maximus and the Arch of Titus, stands the Arch of Constantine, the most impressive triumphal arch ever preserved to this day. The arch was built in honour of Emperor Constantine, to celebrate his victory over Maxentius in 312 AD.
