The parish of Gwinear (Cornish: Sen Gwynnyer), is situated in the Deanery and Hundred of Penwith. To the north is the parish of Gwithian with Camborne also in the north going around to the east. Crowan is to the east going around to the south of Gwinear Parish, with St. Erth and Phillack both lying to the west. This parish lies on high ground south-west of Camborne and is composed of scattered farms and houses. There is archaeological evidence that farming in this area goes back at least to the 2nd century, as a defended farmhouse of that period was discovered in the parish. The village of Rosewarne was once in possession of the Arundells of Lanherne. Gwinear was the son of an Irish pagan king and is reputed to have been slaughtered together with his companions by the Cornish pagan king Theodoric.
Silver and copper mines and related industries were important in the past, but as elsewhere in Cornwall these have now declined. In the 18th and 19th centuries, Rosewarne and Herland mines produced silver, whilst Wheal Alfred and Wheal Relistian produced copper. In those days, the parish was a thriving mining community and one of the first steam engines ever to be built was installed at the Herland mine in 1758. Now the parish has camping and caravan parks and agriculture is the other source of industry.
Villages within the Parish are the Churchtown, Coswinsausin, Drannock, Fraddam, Tregortha, Rewala, Relistian, Carnhell Green, and Wall. The civil parishes of Gwinear and Gwithian were combined to form Gwinear-Gwithian in 1934.
