... has turrets and a rocky peak (7,4)
I believe the answer is:
arthurs seat
'peak' is the definition.
(Arthur's Seat is a peak in Scotland)
'has turrets and a rocky' is the wordplay.
'and' is a charade indicator (letters next to each other).
'rocky' is an anagram indicator.
'has'+'turrets'+'a'='hasturretsa'
'hasturretsa' is an anagram of 'ARTHURS SEAT'.
(Other definitions for arthurs seat that I've seen before include "Edinburgh landmark" , "bit of capital that's raised" , "Hill in Edinburgh" , "Edinburgh rock" , "offering lofty view of capital" .)
