Find your way to the Piazza Venezia, where you'll meet your guide and embark on your 1.5-hour walking tour. First, see Mussolini's office and Napoleon's family palace, before climbing the steps of the Vittoriano.
See the Tomb of the Unknown Soldier and the statues that represent the virtues and regions of Italy adorning this monument to King Victor Emmanuel II. From the top of the monument, get panoramic views of the city and pause for some photo ops before entering the church of Santa Maria in Aracoeli, sections of which are preserved from the ancient Temple of Juno. This Franciscan Temple is a favorite for local weddings, so you just might catch one during your visit.
Visit Michelangelo's Capitol Square, featuring a bronze statue of Marcus Aurelius, the Giant Gemini, the Town Hall, and amazing views over the nearby Roman Forum.
