Allt yr Esgair

Allt yr Esgair is a hill in the Brecon Beacons National Park in Powys [1]. It is commonly referred to locally as simply 'The Allt' [1]. The Welsh name signifies 'wooded slope of the ridge' [1]. It takes the form of a northwest-southeast aligned ridge which rises to a height of 393m and which overlooks the valley of the River Usk to the west and south [1]. Allt yr Esgair's summit is crowned by an Iron Age hillfort, one of several in the Usk Valley [1]. The Roman road between the Roman fort of CICVCIVM at Y Gaer, Brecon and Gobannium at Abergavenny runs along the ridge and is followed by a modern-day bridleway [1].
