We are around 1935, in this photo you can see the intersection between the Via Appia Antica and the Via Ardeatina right in front of the Domine Quo vadis Church (Santa Maria in Palmis). Inside the Church there is a marble slab where footprints are imprinted, legend has it that they should be Jesus’ feet during a meeting with Peter fleeing Nero’s persecutions.

Use the central handle to move the curtain and see the two superimposed images. If it should not be totally visible, it is possible to put it in full screen with the button at the top right of the image.
