Temple, a divine one, toured by old man (6)
I believe the answer is:
pagoda
'temple' is the definition.
(pagoda is a kind of temple)
'a divine one toured by old man' is the wordplay.
'divine one' becomes 'god' (divine being).
'toured by' means one lot of letters goes inside another (tour can mean to go around).
'old man' becomes 'pa' (both can mean father).
'a'+'god'='agod'
'agod' inserted within 'pa' is 'PAGODA'.
(Other definitions for pagoda that I've seen before include "Asian temple with up-turned eaves" , "Pyramidal Asian temple" , "Hindu/Buddhist temple" , "place of worship" , "Pyramid-shaped Hindu temple" .)
