Bank of Scotland (4)
I believe the answer is:
brae
'bank of scotland' is the definition.
(Scottish term for a bank or hillside)
This is all the clue.
(Other definitions for brae that I've seen before include "Steep bank (Scots)" , "Scottish hill slope" , "Upland area in Scotland" , "Bare on Scottish hillside" , "Steep bank or hillside" .)
