This ancient bunker is one the last remnants of the WW2 coastal defences.
However, many in Pentewan still think the war isn't actually over........ and this is now the HQ of the Pentewan Sands Sailing Club, who now act as the Cornish Navy and are the last line of defence against foreign invasion.
They still stand ready to send an armada of skiffs and dinghies out to defend the Cornish coast against any waterborne attack. Their main weapon is a huge stockpile of mouldering Ginsters pasties which they hurl at their enemies in the hope that they flee rather than face death by putrefaction.
It is comforting to know they are still manning the bunkers and keeping us all safe.
