Even more people fit into St. Peter's Basilica, by the way. This impressive church building accounts for almost one-fifth of the entire Vatican City. It is also worth visiting the Vatican Museums with their art treasures from classical antiquity to the Renaissance - and of course the Sistine Chapel, whose ceiling Michelangelo decorated with the world-famous scenes from Genesis. An underground passageway connects the Vatican with the impressive Castel Sant Angelo, which was originally a mausoleum and then served as a fortress.
After visiting one of the world's oldest buildings, the Pantheon, the Forum Romanum and the romantic Trastevere Quarter, you can finally relax in the evening. The Spanish Steps, where you can watch the bustle in Piazza di Spagna, is a great place to do so. And finally you should pay a visit to Neptune at the Baroque Trevi Fountain - just to make sure that it was not the last visit to Rome: To make sure, you simply throw a coin into the well over your right shoulder with your left hand and book the next Nightjet ticket.
