A waterfall on Nant Tawr Fechan beside by Beacons Way in the Fforest Fawr (Great Forest) in South Wales, near to Glyntawe, Powys. The area is known in English as the Great Forest of Brecknock, and was at one time a royal hunting ground. It was the Norman kings who introduced the idea of a ‘forest’, that is, an area of open space ‘outside’ (Latin, ‘foris’, related to ‘foreign’) those legally accessible for ordinary people. Being a ‘forest’ had little to do with being heavily wooded, and several ‘royal forests’, like the Fforest Fawr, lay in upland areas with very few trees.
