Piazza del Popolo takes its name not from the people but, most likely, from the poplar trees that once shaded the spot. For centuries this oval was the first piece of Rome that travellers saw, arriving from the north through the old gate in the Aurelian walls. Giuseppe Valadier gave it its present symmetrical shape in the early 1800s, curving the two long sides into a smooth oval. At its heart rises an Egyptian obelisk older than Rome itself — carved for a pharaoh, shipped here by Augustus, and raised on this spot more than four centuries ago.
Stand at the centre and three streets fan out in front of you, the arrangement Romans call the trident, which sends the traffic on toward the Spanish Steps and the Tiber. Two churches stand on either side of the middle street and look like a matching pair, although they are not: one dome is round and the other oval. Today the square fills with buskers, sketch artists and evening crowds drifting up to the Pincio terrace, where the whole oval spreads out beneath a Roman sunset. Traffic once cut through it; now it belongs again to people on foot.
