The emblematic building is considered the largest Christian church in the world. The site and surroundings attract millions of tourists as Saint Peter’s Basilica is one of the top attractions in Rome.
Reflecting the wealth of the Catholic church its scale is as grand as it gets with hundreds of columns and sculptures around...owe inspiring.
If you decide to go inside, expect the heaviest crowd, noise, security (don't take bags with you that day) and dress appropriately with no shoulder or knees without clothing.
If you go up the cupola for those panoramic views, expect to climb hundreds of steps.
There are guided tours for a hefty price, promising shorter waiting queues, as well as audio tours if you want to do it on your own.
