Cwm

Cwm is a former coal mining village, community and electoral ward three miles south of Ebbw Vale in the county borough of Blaenau Gwent, Wales, within the historic boundaries of Monmouthshire, United Kingdom. In the far north of the community lies Waunlwyd.

The name Cwm is thought to have derived from the farm on the present day nature reserve , Cwm Merddog. Cwm is the Welsh word for valley and the name Merddog is believed to be a corruption of the name of the old farm that used to be here, Troed y Rhiw y Myrdd Fach, which translated means 'the foot of the myriad little hills'. But with the development of the village and coal industry the name was just simply shortened to Cwm. Locally the village to its inhabitants and neighbouring areas is sometimes referred to as The Cwm. A photograph of an old farm house, Troed y rhiw y Myrydd Fach, located behind Tirzah Chapel Cwm, is in Keith Thomas' 'Old Ebbw Vale in Photographs', Vol 2, image 28.
