Way around New Age temple (8)
I believe the answer is:
pantheon
'temple' is the definition.
(pantheon is a kind of temple)
'way around new age' is the wordplay.
'way' becomes 'path' (path is a kind of way).
'around' is an insertion indicator.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'age' becomes 'eon' (eon is a kind of age).
'path' enclosing 'n' is 'panth'.
'panth'+'eon'='PANTHEON'
(Other definitions for pantheon that I've seen before include "building that was built to honour gods" , "Temple of all the gods in ancient Greece" , "list of great names" , "church" , "Ancient Roman temple" .)
