Leaning Tower locale (4)
I believe the answer is:
pisa
'leaning tower locale' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pisa that I've seen before include "Location of leaning tower" , "Italian city with leaning tower" , "Place with leaning tower" , "City with listed building" , "much-visited city" .)
