History
Tonyrefail was a dairy farming and livestock raising area, and many early farmhouses still exist today. This was in stark contrast to the nearby valleys, that were forced to adopt arable and sheep farming activities due to their hilly geography. Early industrialisation began in the late 18th century around a corn mill and woollen factory, but it wasn't until deep coal mining began that employment grew on a large scale. At its peakCoedely Colliery employed nearly 1,800 men which not only changed the face of Tonyrefail, but also created the establishment of nearby colliery settlements such as Coedely and Bryngolau. It was once a busy town in its own right as well as serving the communities of Coedely, Trebanog and Gilfach Goch. It is widely believed that King Edward II was captured by forces loyal to Queen Isabella near Tonyrefail in 1326.
Buildings of note
One of the most notable buildings in Tonyrefail is Collenna House, a three story mansion originally built in 1093, which overlooks the village. The house is believed to have been built by the Welsh noble, Einion ap Collwyn who after a dispute with Iestyn ab Gwrgant, married Iestyn's only daughter, Nest. The two are said to have set up home at Collenna House and it was around this time that they founded the old church of St. John. Collenna House would eventually become home to the Prichard family, who trace their line back to the house's original Norman occupants. One of the more notable members of the Prichard family, who would eventually die at Collenna house, was Reverend Richard Prichard, Vicar of Llandaff. His son, John Prichard was a renowned Welsh architect who was responsible for restoration work at Llandaff Cathedral and many other local churches. To the southwest is Mynydd Maendy, a hill top which contains a wind farm; the admin offices are situated in Tonyrefail. During May 2013 the listed Savoy Theatre, situated on Collenna Road, received permission from Rhondda Cynon TaffCounty Borough Council's Development Control Committee to re-open, having been closed for some 10 years before.
