Pwll Du (meaning a black or dark pool or pit) was a village in Monmouthshire, Wales. It was declared a slum in 1960 and demolished in 1963. The main employment was provided by nearby limestone quarries and by the iron works in Blaenavon. The Pwll Du Tunnel from Blaenavon, once the longest horse-powered tramway in Britain, ended near the village. A pub and the former Welfare Hall, now a school's outdoor pursuits centre, are all that are left standing.
