Nothing says Christmas like Christmas trees, and nothing says Christmas in Rome like the mother of all Christmas Trees located in Saint Peter’s square. Since the Pope holds the environmental issue at heart, this year, the 21-meter high tree will have energy-saving lights. Do all of your Christmas shopping in Rome! Truly, the many markets set up around the city during the holiday season will have more unique gifts than you could. See some Nativity Scenes Christmas wouldn’t be complete without the star of the show (Baby Jesus that is, not Santa Claus.)
