About

Treharris ward lies in the southern part of the Merthyr Tydfil county borough. The area is shaped by the Taff Bargoed Valley, with residential streets following the contours of the hillsides. Historically a coal mining community, its layout and housing reflect this industrial past. The ward includes the main settlement of Treharris itself, along with the neighbouring village of Quakers Yard, which sits at the confluence of the Taff and Bargoed rivers.

A prominent local feature is the substantial viaduct carrying the former railway line, now part of the Taff Trail walking and cycling route through the valley. The landscape is characterised by reclaimed green spaces where former colliery sites once stood. Community life centres around local shops, schools, and sporting facilities, with the wider valley woodlands providing accessible outdoor space for residents.
