The dramatic landscape of the Black Mountain has been shaped by 150 million years of geological history. Layers of sandstone, limestone, and coal-bearing rocks, once formed under tropical seas, were later folded and uplifted into the mountains we see today. During the Ice Age, glaciers carved and smoothed the valleys, leaving a striking terrain rich in geological and industrial heritage. Along the limestone outcrops, lime was quarried and burned for centuries, leaving a legacy of quarry sites across the area. Today, the Black Mountain Quarries form part of the Fforest Fawr Geopark, recognised for their geological importance and cultural history.
