The Vatican has added a very cool feature to its webpage. You can now take a virtual tour of the Vatican necropolis, the excavations of the ancient cemetery that still lies below St. Peter’s Basilica, and which includes the tomb of St. Peter.
It takes a little tinkering to get the hang of exploring around, but it’s as close as you can get to an experience of being there through your computer screen. They’ve done a great job of putting this together. Have a look.
And while you’re at it, if you’re up for a little more, be sure to check out the full text of Margherita Guarducci’s famous book The Tomb of St. Peter, first published in 1960.
