Leaning Tower location (4)
I believe the answer is:
pisa
'leaning tower location' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pisa that I've seen before include "Site of the famous leaning tower" , "City with listed building" , "Italian city with famous tower" , "Location of leaning tower" , "City on the River Arno" .)
