Ruins of the Roman Forum from the Piazza del Campidoglio. The seven pillars in the center are part of the Temple of Saturn. The thick archway just left of the pillars is the triumphal Arch of Septimius Severus, built in AD 203 for the 10th anniversary of the emperor’s accession. On the right side of the photo, to the right of what appears to be a runway (it’s a road), are the remains of the House of the Vestal Virgins. Priestesses tending a sacred flame in the temple lived here.
