About

St Cattwg ward is located in the southern part of the Caerphilly county borough, encompassing the villages of Cwmfelinfach, Wattsville, and Ynysddu. The area is defined by its position within the Sirhowy Valley, with residential streets following the contours of the surrounding hillsides. The landscape is a mix of older terraced housing and more modern developments, with local amenities centered along the main valley road. Community facilities include primary schools, recreational grounds, and local shops serving the resident population.

The ward's history is closely tied to the former coal mining industry, with the landmark Nine Arches viaduct standing as a remnant of the industrial railway that once served the valley. Large areas of green upland common, such as Mynydd y Grug, rise sharply to the east, providing extensive walking routes with views across the valley. The Sirhowy River flows through the ward, and the surrounding woodland areas are managed for public access and nature conservation.
