The Pwll Du Tunnel was the longest horse-powered tramway tunnel to be built in Britain at 1,875 metres (6,152 ft) in length. It started in Blaenavon, Torfaen, Wales, and was originally a coal mine, running northward almost horizontally into a hillside. Later it was extended right through the hill and used to carry limestone from quarries at Pwll Du and Tyla to the ironworks at Blaenavon, and to carry pig iron from Blaenavon to the Garnddyrys Forge. The tramway was extended past Garnddyrys to Llanfoist Wharf on the Brecknock and Abergavenny Canal. The tramway from Pwll Du to the canal fell out of use when the railway came to Blaenavon and the Garnddyrys forge was closed in 1860, but the tunnel continued to be used to carry limestone to Blaenavon until 1926. It is now a scheduled monument and part of a UNESCO World Heritage Site.

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.

Ogof Draenen (Welsh for "hawthorn cave") is, at 66 km (official figure; the true length of passage is still being revised upward, with a modern estimate of approximately 70 km), the longest cave system in Wales and the second longest in Great Britain behind the Three Counties System on the Cumbria/Lancashire/Yorkshire border.The cave was known only as a small entrance on a steep hillside until several years of digging broke through into major passage development in October 1994. It was then explored at unprecedented speed to become the longest known cave in Wales. Ogof Draenen contains a variety of spectacular decorations and some huge passages (the War of the Worlds section is probably the second largest cave passage in Britain). Its large size and occasional complexity make the cave a challenge for even experienced cavers. The cave is managed by the Pwll Du Cave Management Group.

The Abergavenny transmitting station was originally built by the IBA in 1969 as a relay for BBC and ITV VHF 405-line analogue television. It consists of a 46 m guyed lattice mast carrying the aerials at the top. This structure was built on a 440 m hill known as Gilwern Hill overlooking the towns of Gilwern and Abergavenny in Monmouthshire, South Wales. The band III VHF television feeds were provided off-air from St. Hilary and Wenvoe, both near Cardiff. In 1973 the site was enhanced to transmit UHF analogue colour television. The UHF television feed came via a two-hop route from Wenvoe, via the Ebbw Vale repeater. The 405-line VHF television service closed across the UK in 1985, but according to the BBC's and IBA's transmitter list and the BBC's internal "Eng. Inf." magazine, Abergavenny was due to close early - in the third quarter of 1982. Currently, the hill's transmitters provide UHF digital terrestrial TV, VHF FM radio and DAB digital radio. The transmission station is currently owned and operated by Arqiva. Freeview digital terrestrial TV was not available from this transmitter before the digital switchover process began at Wenvoe, with the first stage taking place on 31 March 2010. The second stage was completed on 27 April 2010.
