Crymych
Crymych is a town of around 800 inhabitants as well as a neighborhood (populace 1,739) in the northeast of Pembrokeshire, Wales. It is located around 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 created around the former Crymmych Arms train station on the now-closed Whitland to Cardigan Railway, nicknamed Cardi Bach (Little Cardi). Crymych, which is twinned with Plomelin in Brittany, has a chosen area council. The village has offered its name to a selecting ward of Pembrokeshire that incorporates the towns of Crymych itself and Eglwyswrw.
