About

Cwm is a compact ward situated within the steep-sided Ebbw Fach valley in Blaenau Gwent. Its landscape is defined by the river and the surrounding hills, with residential terraces built along the valley floor and lower slopes. The area's layout and development are directly shaped by its industrial past and the challenging topography of the South Wales Valleys.

The ward's history is closely linked to coal mining and the former Cwm Coke Works. A notable local feature is the Celynnen Mound, an ancient scheduled monument that stands in contrast to the industrial heritage. Community life centres on local facilities like Cwm Primary School and the social club, with the main road running through the valley connecting the area to neighbouring towns.
