Ostia antica

The ancient Roman city of Ostia was in antiquity situated at the mouth of the river Tiber, some 30 kilometres to the west of Rome. The shoreline moved seawards, due to silting, from the Middle Ages until the 19th century. Therefore Ostia is today still lying next to the Tiber, but at a distance of some three kilometers from the beach. Ostia is Latin for "mouth", the mouth of the Tiber. The river was used as harbour, but in the Imperial period two harbour basins were added to the north, near Leonardo da Vinci airport. The harbour district was called Portus, Latin for "harbour".
