Bell tower (6)
I believe the answer is:
'bell tower' is the definition.
(belfry is a kind of bell tower)
This is the entire clue.
(Other definitions for belfry that I've seen before include "Interior of a steeple (where bats hang out?)" , "Where to find peal" , "Ringing tower of church" , "Part of a tower or steeple" , "Place for ringers" .)
