Historical Center: Trevi Fountain, Piazza Navona and Pantheon
The Historical Center is a great place to start touring because it is such an excellent mix of all the different periods that make Rome so famous.
It's amazing to see how all the different Medieval, Renaissance and Baroque piazza's, fountains and facade's fit together, often layered directly upon the still visible ancient ruins of circuses, aqueducts and temples.
It contains such world famous locations as the Pantheon, Trevi Fountain, Piazza Navona and Spanish Steps, but is also full of hidden treasures by such greats as Michelangelo, Bernini, Raphael and Caravaggio.
We'll also take the time for basic fun stuff like pictures and gelato at the best place in all of Rome, best done during the afternoon that people first arrive, as it is a convenient way to force you to stay awake and get you on a good sleeping schedule.
Keep in mind that dresses/ shorts must be below knee level and shoulders covered really only for inside certain churches we'll be entering, so bringing zip on attire/ scarfs is acceptable.
