No leaving construction sets in sacred site (5)
I believe the answer is:
mecca
This clue could be a double definition.
'no leaving construction' is the first definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'sets in sacred site' is the second definition.
The definition and answer can be both locations as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
Can you help me to learn more?
(Other definitions for mecca that I've seen before include "Pilgrim's destination" , "City in Saudi Arabia, chief place of Muslim pilgrimage" , "Mohammed's birthplace" , "Holy place of Islam" , "place many visit" .)
