Being so close by we had a day out visiting Port Isaac, famous for being the setting for Doc Martin and the Poldark series amongst others. It is a tiny but charming place with tight streets, quaint shops and tea rooms along with the craggy tiny harbour. I love these unspoilt harbours that have not changed over the centuries and there is the scent of an age gone by still lingering. The scent of a time when wine was sipped at carved oak tables from golden goblets and the scent of a time of honour and valour, a scent of a time of smugglers and lance and sword, which I suppose is why series like Poldark were set here.
We were fortunate to find that they were filming Doc Martin while we were there and it was fascinating to watch the proceedings as Caroline Catz (Louisa) and baby, the famous dog and of course Martin Clunes, acted out their parts. Martin Clunes kindly posed for a photograph and a brief chat between shoots with nothing being too much trouble and it really topped a lovely day.
