Joined by comedian Matt Lucas for a frenetic 48 hours in the Italian capital. Their first challenge is finding suitable headgear to protect from the scorching Italian sun. They then take a guided tour in vintage Fiat 500 cars, and after wending their way past the Circus Maximus finish atop Gianicolo Hill in time for the cannon being fired - a daily ritual since the 1850s. Next they head to the border of the Vatican, before experiencing the very best of modern Italian cuisine. Day two sees visits to the Trevi Fountain and the Colosseum, perhaps Rome's most incredible antiquity.
