 Itius Portus

Itius Portus or Portus Itius, an ancient Roman name for a port in Nord-Pas-de-Calais, of unknown location.The main candidates have been Wissant and Boulogne, more usually called Gesoriacum, and later, Bononia, but a silted-up lagoon on the Flanders shore behind Calais now seems most likely.
