Porthia is St Ives in English. The Cornish word is made up of porth meaning ‘harbour’ or ‘cove’ and Saint Ia. She was an Irish saint who came over to Kernow (Cornwall) on a leaf or possibly a coracle.
The church is in the centre of the town, close to the harbour and the memorial garden. Very quiet.

Hi Jude, I know the church well, your photographs – I particularly like the wrought iron gate (would like one of those myself!) – are lovely as always. I wasn’t aware of the history behind the name, so thank you! Simone
You are welcome Simone 🙂
