Pembrokshire is located on the southwest coast of Wales. It was established in 1889 following the Local Government Act of 1888. It holds much historical significance, as it was a battleground in the English Civil War in the 17th century as well, and today is remains a location for many prehistoric sites. In is mentioned in the excerpt from Real Wales, in which the speaker comments on how he had met a widely popular novelist who had never visited it before. The tone of this commentary feels as though it contains some shock, making it possible to infer just how historical significant Pembroksire is in Wales. 

"I have also met an extremely well-known north Wales novelist who claimed never to have visited Pembrokeshire. The south. Not Welsh enough. Non-compliance as a political act" (Finch).
