About

Llangennech ward is situated in the southern part of Carmarthenshire, near the tidal estuary of the River Loughor. The area is characterised by a mix of residential housing and pockets of green space, with its landscape shaped by its industrial heritage. The community is connected to neighbouring areas by the A4138 road and local rail services, which run along the edge of the ward.

The local economy has historical links to coal mining and tinplate production. A notable local feature is the large area of saltmarsh and mudflats to the south, part of the Carmarthen Bay and Estuaries Special Area of Conservation. This environment supports birdlife and is traversed by a network of drainage channels. The ward includes the main village settlement and several smaller, outlying residential areas.
