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’.
