Corso Ovidio runs the length of the old town, from the Porta Napoli at one end to the Villa Comunale gardens at the other. It is named for Sulmona's most famous son, the Roman poet Ovid, and is the spine along which most of the town's notable buildings sit. Walking it slowly is the best introduction to Sulmona.
Along the way: the Palazzo dell'Annunziata with its extraordinary Gothic-Renaissance facade, the Cathedral of San Panfilo on a side spur, and the cluster of confetti shops whose windows display elaborate sculpted flowers and figures made from sugar-coated almonds. The street is paved with smooth stone and is largely pedestrian — pleasant in the early evening for the local passeggiata.
