Swiss Valley

About

Swiss Valley ward lies in the southeastern part of Carmarthenshire, centred around the village of Pontyberem. The area is defined by its industrial heritage, historically linked to coal mining in the Gwendraeth Valley. Its landscape is characterised by rolling hills and the presence of the Lliedi Reservoir, a key local feature that supplies water and offers a focal point for the community. The ward includes several smaller settlements, creating a network of residential areas connected by local roads.

The area is named for the Swiss Valley, a local geographical area whose scenery was once likened to Switzerland. A notable landmark is the Grade II listed Swiss Valley Church, a distinctive stone building with a slate roof situated near the reservoir. The local economy has diversified from its historical base, with a mix of small businesses and commuter links to larger towns like Llanelli. The terrain includes areas of woodland and farmland, contributing to its semi-rural character.
