Blackwater () is a village in Cornwall, England, United Kingdom. It is situated in the parish of St Agnes between Truro and Redruth. The village lies on the old course of the A30 north of the current course which bypasses it. The village has a primary school (built in 1877) which serves the village and surrounding settlements. History Over the course of Blackwater's history, the town has supported four public houses: Clinton House, Cornish Miners Inn, The Red Lion and The Spread Eagle. The Chacewater to Newquay railway line (1903–1963) crossed through Blackwater. A station building was located south of Presingoll Barns near St Agnes. In 1972 the railway bridge was destroyed. Geology In an 1824 published geological study, 19th century Blackwell was described as follows: "Descending into a little valley at Blackwater, slate and compact rock present themselves in a section afforded by a ravine. In this valley cultivated fields and a few trees gladden the eye; but this oasis is of little extent; for a steep ascent leads again to the common, which extends as far as Chasewater, over rocks of the same character of..." bright red remains of mining operations. Wheal Concord Commonly known as Wheal Concord, Wheal Concord and Wheal Briton mines are located on the road between Blackwater North Hill and Skinner's Bottom. The founding dates of the mines are unknown, but they both closed and joined forces when they reopened in 1810. The Wheal Concord Silver, Lead and Copper Mining Company Limited was formed in 1860, but due to a drop in the tin market, the mining company closed a few years later. Regarding the late nineteenth century fall of tin prices, Herbert Thomas said of St Agnes mining in his 1896 "Cornish Mining Interviews": In 1980 Nicholas Warrell, having secured £500,000 in investment monies, and Jack Trounson reopened the mines and produced 21,000 tonnes of tin. The year after opening they received a visit from Prince Charles. The mine was only open for a few years, but they had extracted all that they could with their contributors' investments. Wheal Concord was unable to secure the investment of £4,000,000 for machinery and resources to access resources deeper underground and had to close their business in 1986. The mine closed in November 1982. Religion The 18th century Methodist chapel in Blackwater was a simple, earth floored building where women and men sat on different sides
