Removed sod from sandstone in the French port (6)
I believe the answer is:
nantes
'the french port' is the definition.
(I've seen this before)
'removed sod from sandstone' is the wordplay.
'removed' is an anagram indicator (moved again).
'from' indicates named letters should be taken away.
'sandstone' with 'sod' removed is 'anstne'.
'anstne' with letters rearranged gives 'NANTES'.
'in' acts as a link.
(Other definitions for nantes that I've seen before include "Port city on the Loire estuary" , "Site of historic drownings" , "Loire port; an old Edict" , "A major French port" , "Western French port" .)
