The Trevi Fountain, a renowned and exquisite Roman landmark, dates back to 19 BC, but its present form dates to 1762. Tossing a coin over your left shoulder ensures a return to Rome. I've experienced its beauty day and night but missed its recent cleaning.
Venice Square, though controversial due to the relocation of the Venice Palace, is incredibly beautiful. Despite traffic, it's worth a nighttime visit for its enchanting illumination and quieter atmosphere.
Piazza Navona, a Baroque gem, resides in the heart of Medieval Rome. Accessible through narrow alleys, it boasts fountains, an obelisk, flea markets, street artists, and bustling cafes, but beware of touristy prices.
Its importance waned with the construction of Termini station. The square is spacious, housing a 24-meter-high Egyptian obelisk. Visit Santa María del Popolo church for Caravaggio's masterpieces and Renaissance artworks, including two similar-looking temples.
Despite the crowds, experiencing the Sistine Chapel is essential. I've been twice with guides and learned fascinating details. Plus, guided tours help you skip the lines. Vatican City, the smallest European state, encompasses St. Peter's Square.
