Lustre surrounding top of Russian place of worship (6)
I believe the answer is:
shrine
'place of worship' is the definition.
(shrine is a kind of place of worship)
'lustre surrounding top of russian' is the wordplay.
'lustre' becomes 'shine' (I've seen this before).
'surrounding' indicates putting letters inside.
'top of' indicates taking the first letters.
The first letter of 'russian' is 'r'.
'shine' going around 'r' is 'SHRINE'.
(Other definitions for shrine that I've seen before include "temple" , "Hallowed place associated with a sacred thing or person" , "Holy place with special associations" , "Place hallowed for special associations" , "burial place?" .)
