Hisory: Iron age c800 BC to 43 AD (Talybont on Usk)
Hill top forts with concentric rings of earthen banks characterise these structures. Local groups of families would have lived securely with their livestock within the ditches and wooden palisades. There is clear evidence of these on top of the Allt yr Esgair and the Wenallt above Talybont. Two further sites have been partially covered by forestry marked as settlements at Grid References SO/091193 and SO/098217 .
