A stitched mosaic of Saint Peter's Square, in Vatican City, the papal enclave within Rome, Italy, as seen from the top of St. Peter's Basilica. The area was redesigned by Gian Lorenzo Bernini, from 1656 to 1667, and was extended by the Via della Conciliazione (seen leading out of the plaza here), Mussolini's grand avenue of approach.Photo credit: Diliff
