Craig y Cilau is a limestone escarpment in the Brecon Beacons National Park in Powys, Wales. It was declared a national nature reserve in 1959 because of its importance for wildlife, particularly plants. It is situated on the north side of Mynydd Llangatwg in Llangattock community, about 2 miles (3.2 km) south-west of Crickhowell. The reserve covers 157 acres (0.64 km2) and has a varied geology with Old Red Sandstone below the cliffs and Millstone Grit above them. The range of habitats is equally wide with woodland and scrub in the lower parts and moorland higher up. There are numerous caves and disused quarries along the escarpment. The limestone cliffs are home to many scarce plants including maiden pink (Dianthus deltoides), hutchinsia (Hornungia petraea) and the most southerly British population of alpine enchanter's nightshade (Circaea alpina). Five species of whitebeam occur including the narrow-leaved whitebeam (Sorbus leptophylla) and lesser whitebeam (Sorbus minima) which are endemic to Wales. About 50 species of bird breed on the reserve including ring ouzel and raven on the cliffs and redstart, wood warbler and pied flycatcher in the woods. One of the caves, Agen Allwedd, holds a roost of lesser horseshoe bats during the winter months.

The Brynmawr rubber factory is a now-demolished building which was situated in Brynmawr in Blaenau Gwent, Wales. It was designed and constructed between 1946 and 1952 by the Architects' Co-Partnership, a group of architecture alumni from the Architectural Association in London, in collaboration with engineer Ove Arup. Featuring a nine-domed concrete ceiling, the building was part of the "Festival of Britain period" in architecture and became the first post-war building to receive listed status, with a Grade-II* designation in 1986. Despite this status, the building was demolished in 2001 leaving only the boiler house intact, and the site is now occupied by housing and a superstore. The building was commissioned by the industrialist Lord James Forrester for Enfield Cables, of which he was a director. Forrester had been part of the pre-war Brynmawr Experiment, which aimed to revive the town following the Great Depression. His desire for regeneration led to his decision to situate the factory in Brynmawr, despite it not being the best location commercially. Enfield Cables were not able to make the site economically viable after opening, and it was taken over by the Dunlop Rubber Company, operating under the brand name Dunlop Semtex. Dunlop Semtex achieved success with the factory, producing flooring for the health and education sectors, going on to buy the site in 1964. A downturn in fortunes in the late 1970s and early 1980s led to the factory's closure in 1981.

The River Clydach is a short, steep and fast-flowing river in Monmouthshire and the county borough of Blaenau Gwent in south Wales. It lies within the Brecon Beacons National Park. It is around 10 kilometres (6 mi) in length. The river rises on the southern slopes of Mynydd Llangatwg (51.8122°N 3.1939°W / 51.8122; -3.1939 (River Clydach, source)) then heads south-east through Clydach Dingle past Brynmawr. It then enters the spectacular Clydach Gorge, dropping about 300 metres (1,000 ft) to Gilwern and its confluence with the River Usk (51.8329°N 3.1007°W / 51.8329; -3.1007 (River Clydach, mouth))."Clydach" is a common name for watercourses in south Wales and is thought to derive from an old Welsh word for "swift" or possibly "stoney", both of which would apply in this case.
