Relocated in same French city (6)
I believe the answer is:
amiens
'french city' is the definition.
(I've seen this before)
'relocated in same' is the wordplay.
'relocated' indicates anagramming the letters.
'in'+'same'='insame'
'insame' anagrammed gives 'AMIENS'.
(Other definitions for amiens that I've seen before include "capital of Picardy" , "French cathedral city on the river Somme" , "City of NE France" , "European town" , "French town" .)
