Built, as ordered, around new city in Turkey (8)
I believe the answer is:
istanbul
'in turkey' is the definition.
('Istanbul' is part of 'turkey')
'built as ordered around new' is the wordplay.
'ordered' indicates an anagram.
'around' means one lot of letters goes inside another.
'new' becomes 'n' (abbreviation as in New Testament NT).
'built'+'as'='builtas'
'builtas' with letters rearranged gives 'istabul'.
'istabul' enclosing 'n' is 'ISTANBUL'.
'city' is the link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for istanbul that I've seen before include "Take the Latin bus out to Turkey" , "foreign port" , "Catch the Latin bus out to Turkey" , "City formerly known as Constantinople" , "City in both Europe and Asia" .)
