Diffwys a Maenofferen

About

Diffwys a Maenofferen ward is located in the historic slate-quarrying town of Blaenau Ffestiniog. The area is dominated by the immense, terraced slopes of former slate workings, creating a stark and industrial landscape. The ward encompasses residential streets that climb the hillsides, with many homes built from the local grey stone. This terrain defines the community's character, shaped by its extractive past.

The ward includes part of the Llechwedd Slate Caverns, a major visitor attraction based in deep mine tunnels. The area's economy has shifted from active extraction to tourism and heritage. Remnants of the industry, including tips and abandoned structures, are widespread. The surrounding high moorland of the Migneint area provides a contrasting natural backdrop to the man-made topography.
