The Orne (Ptolemeus Olina[citation needed]) is a river in Normandy, within northwestern France.[1] It discharges into the English Channel at the port of Ouistreham. Its source is in Aunou-sur-Orne, east of Sées. The Odon is one of its tributaries.
The Orne flows through the following departments and towns:
- Orne (named after the river): Sées, Argentan
- Calvados: Thury-Harcourt, Caen, Ouistreham
Name
The name of the Orne river in Normandy, which is referred to as the Olina by Ptolemy, is a homonym of Fluvius Olne, the Orne saosnoise in Sarthe, which Xavier Delamarre traces back to the Celtic olīnā (elbow).
