This is a free walking tour around Rome. Most tours that you have to pay for do not tell you about the history around it, but this tour does. The tour gives a history of the city, an introduction to Christianity and origins of Rome. The tour is about 3hrs long but it covers Porta del Popolo, Piazza del Popolo, the Tomb of Augustus, the Pantheon, Piazza Navona, Fountain of the Four Rivers, Ponte, Sant'Angelo, Castel Sant'Angelo, and gives an introduction to the Vatican. The tour guides also give recommendations to places to eat, visit, nightlife locations, and discounts towards the skip-the-line Vatican tour. I highly recommend the Rome's Ultimate tour. You would have to make reservations online ahead of time. read more
