### Clue: The leaning tower of Pisa? (6,8)
### Answer: LISTED BUILDING 
 ### Explanation: Definition: The leaning tower of Pisa
 Cryptic defn: Reference to the list;the leaning to one side of that famous building, and to the Statutory List of Buildings of Special Architectural or Historic Interest in the UK of conserved buildings which cannot be demolished, or even altered, without special permission from the relevant authorities. And that tower will surely be on the Italian equivalent of the list, or something like it.
