Cold Lane maybe starts in the empty ruined arcade (8)
I believe the answer is:
cloister
'arcade' is the definition.
(I've seen this before)
'cold lane maybe starts in the empty ruined' is the wordplay.
'cold' becomes 'C' (eg on taps).
'lane maybe' becomes 'Lois' (Lois Lane from Superman).
'starts in' says to take the initial letters.
The first letters of 'the empty ruined' is 'ter'.
'c'+'lois'+'ter'='CLOISTER'
(Other definitions for cloister that I've seen before include "Walkway round church etc" , "Covered walk round quadrangle" , "'Religious retreat, a convent, say (8)'" , "Covered walkway around courtyard" , "Covered walk by cathedral etc" .)
