Rhondda Cynon Taf (Welsh pronunciation: [ˈr̥ɔnða ˈkənɔn ˈtaːv]), or RCT, is a county borough in the South Wales Valleys of Wales. It consists of 3 valleys: the Rhondda Valley, Cynon Valley, and Taff-Ely Valley. Results from the 2011 census showed 19.1% of its 234,410 residents self-identified themselves as having some ability in the use of the Welsh language.[1]

The county borough borders Merthyr Tydfil and Caerphilly to the east, Cardiff and the Vale of Glamorgan to the south, Bridgend and Neath Port Talbot to the west and Powys to the north. Its principal towns are - Aberdare, Llantrisant with Talbot Green and Pontypridd, with other key settlements/towns being - Ferndale, Hirwaun, Llanharan, Mountain Ash, Porth, Tonypandy, Tonyrefail and Treorchy.

See List of places in Rhondda Cynon Taf for a list of towns and villages. The most populous town in Rhondda Cynon Taf is Aberdare (Welsh: Aberdâr) with a population of 31,705 (2001 Census), followed by Pontypridd with 29,781.


The county borough was formed on 1 April 1996, by the merger of the former Mid Glamorgan districts of Rhondda, Cynon Valley and Taff-Ely (with the exceptions of Creigiau and Pentyrch, which were added to Cardiff). Its name reflects all these, and thus also the rivers Rhondda, Cynon and Taff.


The district developed from the discovery and mining, primarily for export, of high-quality Welsh coals, such as steam coal, via Cardiff and Barry docks. The landscape was dominated by coal-waste heaps and deep mine pit-heads. Many of the roads are lined with semi-ribbon development of closely packed Victorian terraces of houses which have given the Rhondda and Cynon valleys their distinctive appearance. In the nineteenth century the Rhondda had over 60 mines.

As deep mines closed, a number of very large open-cast coal mines were created and remain in operation, especially towards the north of the area.

The Welsh Development Agency, which was formed in 1976 to help reverse the economic down-turn in Wales caused by the recession in both the coal and steel industries, was very active in the Rhondda Cynon Taf area in supporting and encouraging industrial and commercial regeneration. Recent investment in the area has included the Dragon International Film Studios, on the site of Llanilltyd open-cast mine. This project is headed by Sir Richard Attenborough and will comprise TV studios, editing suites and a large film studio complex. The location of the project has led it to become known locally as "Valleywood", even though the Welsh valleys are some miles away.


The coal industry has had major adverse impacts on the quality of the environment, such that most of the rivers were severely polluted to the exclusion of all fish life. Recent decades have shown great improvement with the return of salmon recorded in the River Taff and the River Rhondda but the continued presence of man-made obstacles in the rivers is inhibiting regeneration of their pre-industrial numbers and condition.

The chemical industry has also had adverse effects due to the dumping of toxic waste in the now disused Brofiscin Quarry in the village of Groes-faen. Dumping took place over a 6-year period between 1965 and 1970 by the Monsanto Company.[2] It is estimated that the cleanup costs could be more than £100 million. A Dr Papageorge, formerly Monsanto's chief scientist, estimates that between 60,000 and 80,000 tonnes of PCB contaminated wastes were dumped there.[3]


The area is governed by Rhondda Cynon Taf County Borough Council from headquarters in Clydach Vale and is the host Authority to the South East Wales Improvement Collaborative (SEWIC), Excellence Wales award winner 2010. The Rhondda Cynon Taff has 4 MPs represented in parliament. There are also 4 constituencies represented in the National Assembly. All of the MPs and AMs of the Rhondda Cynon Taff are members of the Labour Party.
