Let's explore inside the Papal Basilica of St. Peter in the Vatican simply known as St. Peter's Basilica. It is considered as the largest church in the world, an Italian Renaissance church located in Vatican City, the papal enclave within the city of Rome. Considered as one of the holiest Catholic shrines, it is holding a unique position in the Christian world as the greatest of all churches of Christendom.
Although I'm not a Roman Catholic by religion, this sacred church was indeed a highlight of my Europe tour. Many Christians would love to visit this place & experience the holiness of Vatican City. A one day tour specifically to St Peter's Basilica is highly recommended to fully explore the place. There's so much to explore in the beauty, secret and historical content of this Basilica.
