The city of Kélibia (Qulaybiyah) rests on Cap Bon, Tunisia, and points the explorer in the direction of Sicily. The site was founded by the Carthaginians in the first millennium and recognized by the Romans as either Clypia or Aspis.
While Kélibia is famous today for its fine beaches and fishing, in the classical period it had another association. It was near here that the Romans first landed after defeating the Carthaginian navy in 255 BC. Aspis was besieged, but quickly surrendered. It was a notable "first" in the course of the First Punic War, something the Romans crowed about.
