Saint Peter’s Dome optical illusion in Rom can be captured from Via Nicola Piccolomini. One thing worth noticing is that when the viewer moves toward the dome, it looks like the shape is getting smaller, which quite strange. There seems to be a phenomenon where this is more extreme when seen from a car and is owing to the arrangement of the edifices on the street. This is something quite special and indeed interesting to observe when in sy i.e. in Rome.
