Saint Peter's Square, located in the heart of Vatican City, is a must-visit destination for any traveler interested in history, architecture, and religion. Easily accessible by public transport, with the Ottaviano metro station nearby, the square serves as a gateway to Saint Peter's Basilica. While visiting, consider starting early in the morning to avoid crowds, especially during peak tourist seasons from Easter to October. Entry to the square is free, but guided tours are recommended for those interested in detailed historical and artistic insights. Allow around two to three hours to explore the square and its surroundings. It's advisable to book tours in advance to secure a spot, especially during major religious events or papal audiences. Dress modestly, as the Basilica has a strict dress code, and be prepared for security checks.
