Battering ram opened front (9)
I believe the answer is:
promenade
'front' is the definition.
'battering ram opened' is the wordplay.
'battering' indicates an anagram.
'ram'+'opened'='ramopened'
'ramopened' anagrammed gives 'PROMENADE'.
(Other definitions for promenade that I've seen before include "Seafront walk" , "dance" , "Esplanade" , "Place for strolling by the sea" , "Seaside walkway" .)
