It is also the name of the quarry village at the base of the hill situated at the edge of Snowdonia National Park at grid reference SH600656.
Many of the houses are spread along long roads rather than clustered around a point, giving the village a somewhat decentralised feel.
However the village is distinguished by two parallel rows of semi-detached quarrymen's cottages constructed during the 19th century for workers of Penrhyn Quarry, which mined slate.
Each of the houses was provided with an area of land (approximately 1 acre) sufficient to feed the family.
This can be contrasted with the situation in the South Wales coalfields or in the industrial Midlands where no such provision was made for the workers.
