Tuscan hill town (5)
I believe the answer is:
siena
'tuscan hill town' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for siena that I've seen before include "somewhere in Italy)" , "Italian city strangely in sea" , "city in Italy" , "Tuscan town" , "Walled city of Tuscany" .)
