The Bryn Banog mountain wall

A named place photographed at this map point in Gwynedd.

Roughly 300 meters in height, The Bryn Banog mountain wall is composed primarily of Silurian slate, common to the geology of north Wales. It may derive its name from early Welsh terms suggesting a "hollow hill," a reference possibly linked to local folklore surrounding hidden or otherworldly places. Its prominence contributes to the distinctive landscape of the Gwynedd area.
