Before the rapid industrialisation of the early nineteenth century, Cwmdare was a small rural village in the parish of Aberdare. The parish was described as "very remarkable" for the
Taplasau Hâf (summer games) which had taken place on feast days since at least the 1640s. Cwmdare was noted as one of three sites set aside for such games, this site was the
Ton-glwyd-fawr located near the centre of the village. Today this area is known colloquially as 'The Ton' and a pub of the same name is situated near by. By the mid-nineteenth century, the
Industrial Revolution was fuelling the demand for Aberdare coal. Several deep coal mines appeared around Cwmdare, and families began to move into the area from other parts of Wales looking for work. The new miners needed housing, and between 1853 and 1859 the first streets were laid down on the west side of the Dare Valley, these would become the centre of the modern village. A few houses were also built on the east side of the valley, near the Merthyr Dare Colliery, known as Pithead. As the colliery activity increased so did the need for housing, and rows of terraced miners' cottages were built to the north-west. Cwmdare had four large collieries: the Cwmdare, Merthyr Dare and
Bwllfa Dare collieries were all sunk in the 1850s, while work began on
Nantmelyn Colliery in 1860. Over the next 120 years, the seams in the Maerdy mountain were gradually used up, with Merthyr Dare closing in 1884, Cwmdare in 1936, Nantmelin in 1957, and finally Bwllfa Dare in 1977. == Post-mining ==
