Via Julia Montana (Margary 623,62a,62b,612b,621)

Via Julia Montana was a Roman road stretching across South Wales from Carmarthen (Moridunum) in the west to Burrium (Usk) in the east, traversing the interior uplands rather than following the coastal corridor. Along its route, it passed through key settlements such as Brecon (Cicucium or Y Gaer) and Abergavenny (Gobannium), linking military forts, civilian settlements, and river crossings across the mountainous terrain. The road provided a strategic inland route that complemented the coastal Via Julia Maritima, facilitating troop movements, trade, and communication between Roman forts in the heart of Wales.

Archaeological evidence—including traces of aggers, cropmarks, and alignments preserved in the landscape—supports its existence, although much of the precise route remains partly conjectural due to the rugged terrain and fragmentary survival of physical remains.
