Entrance to the "scavi" in the
Vatican. The ring indicates where the St. Peter square obelisk originally stood - in the center of the circus of Nero.
St. Peter died here and was buried at the road beside the circus - where Saint Peter's main altar stands today.

St. Peter died here and was buried at the road beside the circus - where Saint Peter's main altar stands today.
This is a very useful graphic - the original obelisk position is pointed out... the tomb was on the road immediately beside the circus - (where the main altar is now)
This is how the Basilica looked like before the time of Michelangelo (a bit like San Paolo fuori le mura) - note the obelisk to the left in its original position
