Admission to St Peter's Basilica is free, but there are associated costs for visiting the dome and for any audio guides or guided tours.
St Peter's Basilica, located in the Vatican, is one of the most famous and visited churches in the world. There is no charge to enter the basilica itself, making it accessible to all visitors. However, if you wish to climb the Dome, which offers a breathtaking panoramic view of Rome and the square in front of it, you will have to pay a ticket. The cost to go up on foot is about 8 euro, while if you choose to use the lift for part of the route, the price rises to about 10 euro.
Furthermore, if you wish to deepen your visit, you can opt for an audio guide, which usually costs around 7-10 euros, or join a guided tour, which may vary depending on the agency and the duration of the tour. These tours may also include other nearby attractions, such as the Vatican Museums and the Sistine Chapel, offering a more complete experience. It is advisable to book in advance, especially during the peak tourist season, to avoid long waits.
