About

Cwm-twrch is a ward in the upper Swansea Valley, primarily containing the villages of Cwmtwrch and Cwmtwrch Isaf. The area is defined by the steep, forested slopes of the surrounding hills, with the River Twrch flowing through its centre. The landscape is a mix of residential housing and remnants of its industrial past, with old stone terraces built for the local workforce. The community is closely connected to the river and the surrounding natural environment.

The ward's character is shaped by its location within the Brecon Beacons National Park, influencing its development. Former collieries and quarries are now largely reclaimed by nature, forming part of the valley's green backdrop. A specific local feature is the Craig-y-Nos Country Park, located just to the north, which includes woodlands and the river. The area serves largely as a residential community for the wider valley, with strong historical ties to the South Wales coalfield.
