Description :
Pwll du Tunnel carried Hill's tramroad from Blaenavon Ironworks through the mountain to Pwll du, connecting it with the Pwll Du limestone quarries, Garnddyrys Forge and the Brechnock and Abergavenny Canal. The tunnel probably originated as a mining level which by 1800 already extended 3/4 of a mile into the mountain. It was connected through to Pwll Du by c1815 when it began use as tramroad replacing the former mountain route from the quarries to the Ironworks. The route extended to the canal by 1821 and continued in use until the 1860s.
There were 2 tunnel entrances at the N end, each emerging just E of the metaled road. The more N has a stone portal (walled up) and short approach cutting. The S portal appears as a limestone wall roughly 50m to the SE, the arch being covered by soil.
The area includes the Tunnel House and the lines of tracks and tramroads.
