Except for a badly damaged theater, practically nothing remains of the ancient town, which was a very important port in the Roman period and no doubt even before. Ruins were seen at the beginning of the French occupation but they have disappeared under the modern town.
As with Rusguniae and Rusucurru, the root Rus suggests a Punic settlement or Punicized native town. There is, however, no trace of archaeological evidence. The attribution of coins with a Punic legend to the town remains hypothetical.
