The railway between Abergavenny-Brynmawr presented a lot of challenges during its construction in the 1850s and early 1860s cutting into the hills by Clydach gorge and tunnelling bores into rock several times. When it closed in 1958 everything apart from the structures were removed, today the tunnels and key supports are all that remain as the old trackbed is now being used as a public footpath.
