Porthdinllaen is a small coastal village in the Dwyfor locality on the Llŷn Peninsula within Gwynedd, Wales, located on a small promontory, and historically in Caernarfonshire. It is near the larger village of Morfa Nefyn. It has been owned by the National Trust since 1994. With views across to Yr Eifl and Snowdonia, Porthdinllaen, with Nefyn and Morfa Nefyn, form a magnificent of sweeping bay. There are only about two dozen buildings at Porthdinllaen, with the Tŷ Cochpub the centre of the village. Vehicular access to the village is restricted to residents with a car permit; visitors must walk across the beach from Morfa Nefyn or across the Nefyn & District Golf Clubgolf courseon top of the headland, past the Iron Age hill fort.
Port
Porthdinllaen was originally a fishing port, based around a natural harbour at the west end of a bay over a mile and a quarter across, and with over of safe anchorage. The harbour is sheltered by a headland jutting out to the north from all but a north-easterly wind, and as the only such haven on the Llŷn Peninsula, it has been used for many centuries of trading, and as a place to run to for shelter in a storm. In May 1806, a parliamentary bill approved new buildings when it seemed that Porthdinllaen would be chosen as the port on the route to Ireland, rather than Holyhead, Anglesey. Porthdinllaen was almost as far west as Holyhead, but Holyhead was more accessible, due to Thomas Telford's road developments. Porthdinllaen Harbour Company was formed in 1808 in preparation, by the Jones Parry family of the Madryn estate, but the bill before Parliament to constitute Porthdinllaen as a harbour for Irish trade was rejected in 1810. Pig farming was important to the economy of the Llŷn Peninsula, and Porthdinllaen was the main point of export to Liverpool. In 1830, the farmers and merchants asked the Madryn estate to build a bigger pier, but the estate refused. The first steamer, the "Vale of Clwyd", did not therefore enter service until 1832. Apart from goods intended for the local population and the farmers, Porthdinllaen imported large quantities of salt to create the Nefyn herring.
Railway proposals
After the failure of the proposal to create a point of embarkation to Ireland, various proposals were made to build railways to serve the harbour at Porthdinllaen. However, none was eventually constructed:
1845 - The Worcester and Porth-Dynllaen Railway informed the Rev. T. Parry Jones Parry of an application to Parliament of a railway track from Worcester to Porthdinllaen
1845 - The North Wales Railway Co. planned to construct of track from Bangor to Porthdinllaen
In the 19th century, north Wales lacked good roads, and so the sea was the easiest way to access many places. Porthdinllaen, on the northern coast of the Llŷn peninsula, with its sheltered north facing bay, became important as a harbour of refuge and a busy port, with over 700 ships passing through the port in 1861. After storms in 1863, the local parish priest wrote to the Royal National Lifeboat Institution to request that a lifeboat be positioned in the harbour. The boat shed and slip were commissioned in 1864. Manned constantly since, the current coxswain is Mike Davies, who has served as coxswain since 2004. The current Tyne class lifeboat "Hetty Rampton", in service since 27 April 1987, is currently being replaced by a new Tamar class lifeboat "John D Spicer".
Film location
Due to its highly preserved and yet maintained status, Porthdinllaen regularly acts as a film and television shooting location. In September 2004 it posed as a Scottish fishing village for the Demi Mooreromantic thrillerHalf Light.
