One late afternoon in middle of July 2021 (very hot), we did the
9-Piazzas tour with a Brazilian Architect (Pedro Senna) who lives in Rome and considers it along with its history & architecture as the school of his dreams. The informative tour explains history of 2 millennials of Rome through these 9 piazzas. The 3km walking tour not only leads you through 9 Roman squares but also their surrounding monuments, Baroque Churches and Palaces:
1. Piazza della Repubblica
2. Piazza di San Bernardo
3. Piazza Barberini
4. Piazza del Quirinale
5. Piazza di Trevi
6. Piazza di Pietra
7. Piazza di Sant'Ignazio di Loyola
8. Piazza della Rotonda (Pantheon)
9. Piazza Navona
Pedro opened my eyes as to what happened to Rome for a millennium between 400 AD - 1400 AD through his historical narrative of the 9 Piazzas. Great educational yet fun tour that is highly recommended to whoever want to understand Roman history and architecture.
