About

The Sirhowy area in Blaenau Gwent is defined by the Sirhowy River and the valley it carves through the uplands and settlements around Tredegar. Industrial activity from the 18th and 19th centuries—ironworks, collieries and tramroads—shaped the layout of streets and lanes; many former transport alignments are now foot and cycle routes within Sirhowy Valley Country Park and the waymarked Sirhowy Valley Walk. Tredegar’s association with Aneurin Bevan and its mining and ironworking past are reflected in local place names and public collections, and small bridges and culverts trace the river’s historic course through the town.

Today the valley contains pockets of woodland, reclaimed spoil, and a continuous river corridor used by walkers and cyclists. Old rail embankments serve as green links and interpretation panels explain industrial processes and everyday life in the valley. Community groups run conservation tasks and heritage events, while upper slopes are used for grazing and houses sit along the valley floor, connected by local roads and bus services within Blaenau Gwent.
