Llanrhian

The north Pembrokeshire community of Llanrhian includes the farming village of Croesgoch, the seafaring settlement of Trefin and the little slate-exporting harbour of Porthgain.

Sketch map compiled by Croesgoch History Group showing the location of WW2 Home Guard sandbag pill-boxes between Croesgoch and St. David’s.

Although Trefin is set back from the cliffs, it had close links to the sea via the inlets of Aberfelin and Abercastle and was a centre of smuggling in days gone by. The ruins of a mill are preserved at Aberfelin – one of two in the area owned by the bishops of St David’s. Porthgain still has many relics of its industrial past as a slate and granite exporting harbour and also the remains of a brickworks once capable of producing 50,000 bricks a week. Local legend has it that during the First World War, German U-Boats called in regularly at remote coves along the coast in order to replenish supplies of fresh water. Croesgoch has an active local history group which has access to a number of documents relating to military heritage, including Home Guard record books and photographs. There is also a Heritage Group in Trefin.
