Force way through seaside attraction by church (6)
I believe the answer is:
pierce
'force way through' is the definition.
(as in piercing through something)
'seaside attraction by church' is the wordplay.
'seaside attraction' becomes 'pier' (structure by the sea).
'by' is a charade indicator (letters next to each other).
'church' becomes 'CE' (abbreviation for Church of England).
'pier'+'ce'='PIERCE'
(Other definitions for pierce that I've seen before include "Perforate" , "go through" , "Penetrate as with pin" , "Punch" , "Make hole in for recipe" .)
