Ancient land in eastern France (7)
I believe the answer is:
alsatia
'ancient land in eastern france' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for alsatia that I've seen before include "old criminal sanctuary" , "and German shepherds?" , "One-time refuge for criminals" , "Place giving name to German shepherd dogs" , "area around Whitefriars, once" .)
