Crymych
Crymych is a village of around 800 inhabitants and a community (populace 1,739) in the northeast of Pembrokeshire, Wales. It is positioned roughly 800 feet (240 m) over sea level at the eastern end of the Preseli Mountains. It stands astride the old Tenby to Cardigan turnpike road, now the A478. The village developed around the former Crymmych Arms railway station on the now-closed Whitland to Cardigan Railway, nicknamed Cardi Bach (Little Cardi). Crymych, which is twinned with Plomelin in Brittany, has actually an elected neighborhood council. The town has actually offered its name to a selecting ward of Pembrokeshire that includes the villages of Crymych itself and Eglwyswrw.
