. . . "The Douve or Ouve is a river, 79 kilometres in length, which rises in the commune of Tollevast, near Cherbourg in the department of Manche. Ouve is considered its old name (Unva in ancient texts): Ouve appears to have been misspelled over the course of time as \"Douve river\" and then as \"River of the Douve\" (Douve literally means Ditch)."@en . . .
