St Uny, (Cornish: Rysrudh Sen Uni), is the original church of Redruth town parish. However as Redruth grew into a town, the church and its supporting civil administration proved too small for the increasing population, so the parish was sub-divided to make administration and support more effective.
Redruth, St Uny ecclesiastical parish was created from the remaining part of the original Redruth parish in 1884, when that original parish was divided. (See also Treleigh created 1871, and Redruth St Andrew created in 1883).
The parish name is sometimes spelled St Euny. The origin of the name Redruth is believed to be 'red ford', from the Cornish rys or rid meaning red, and rudh meaning ford. In the past the town of Redruth and its neighbour, Camborne, served the important areas of tin mining area in south-west Cornwall. There has been a long tradition of rivalry between the two towns. In the early days of mining Redruth thought it was a cut above Camborne, because it was the place where the better classes lived. Today Redruth is a small industrial and commercial centre that is by-passed by the A30 trunk road.
