Where: The Roman town at Aldborough (near Boroughbridge, Yorkshire) at SE406664, where Dere Street crossed the river Ure.
Name origin: Presumably the river Ure was originally called something like Isara, discussed under Isca. Delamarre (2003:191) characterised Isara as Indo-European but not Celtic and translated it as ‘impetuous, rapid’.
