After breakfast we'll head directly to St. Peter's Basilica in the Vatican, originally built by Constantine the Great in 324 AD, then reconstructed between 1506 and 1615 under the direction of several famous architects including Bramante, Raphael and Michelangelo.
You may also join the optional Sistine Chapel tour to view Michelangelo's famous frescoes. An optional guided tour of the Colosseum, built in 72 AD, comes highly recommended.
Other highlights include the Arch of Constantine and the Pantheon.
We'll make a wish at Trevi Fountain and take in the romantic vibe at the Spanish Steps. After our tour of Rome, we'll hop back on the bus and head to Florence for a good night's sleep.
