Church in the morning: on top of that cathedral city views showing famous avenue (6,7)
I believe the answer is:
champs elysees
'famous avenue' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'church in the morning on top of that cathedral city views' is the wordplay.
'church in the morning on top of' becomes 'champs' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'that cathedral city' becomes 'Ely' (English city with a cathedral).
'views' becomes 'sees' ('see' can be a synonym of 'view').
'champs'+'ely'+'sees'='CHAMPS-ELYSEES'
'showing' is the link.
Can you help me to learn more?
(Other definitions for champs elysees that I've seen before include "Parisian way" , "way, overseas" , "route to The Arc" , "elegant thoroughfare in Paris" , "Heaven in Paris?" .)
