It's scary going round part of a church (8)
I believe the answer is:
sacristy
'part of a church' is the definition.
('sacristy' is part of 'church')
'it's scary going round' is the wordplay.
'going round' indicates an anagram.
'its'+'scary'='itsscary'
'itsscary' is an anagram of 'SACRISTY'.
(Other definitions for sacristy that I've seen before include "Room in church for vestments etc." , "Vestry" , "Satyr (sic) found in church storage room" , "Church robing room" , "Church's sacred vessels store" .)
