New shrine and old court in Jerusalem (9)

I believe the answer is:

sanhedrin

I'm a little stuck... Click here to teach me more about this clue!

'old court in jerusalem' is the definition.
I can't judge whether this definition defines the answer.

'new shrine and' is the wordplay.
'new' indicates anagramming the letters.
'shrine'+'and'='shrineand'
'shrineand' with letters rearranged gives 'SANHEDRIN'.

Can you help me to learn more?

(Other definitions for sanhedrin that I've seen before include "Ancient court" , "Jewish council" .)

I've seen this clue in the Sydney Morning Herald.
