Town memorably built on lies? (6,7)
I believe the answer is:
melton mowbray
'lies?' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'town memorably built' is the wordplay.
'built' indicates an anagram.
'town'+'memorably'='townmemorably'
'townmemorably' anagrammed gives 'MELTON MOWBRAY'.
'on' is the link.
(Other definitions for melton mowbray that I've seen before include "Pork pie town" , "Centre of stilton" .)
