HER Number:MDV126819
Name:Tin streamworks on Fardel Moor, Cornwood

Summary

Earthworks of pits, ditches and mounds, interpreted as evidence of a possible medieval or post-medieval alluvial tin streamworks, are visible on aerial photographs taken from 1947 onwards and on visualisations derived from lidar data captured between 1998 and 2017.

Earthworks of sub-oval and irregularly shaped pits, ditches and mounds are visible on aerial photographs taken from 1947 onwards and on visualisations derived from lidar data captured between 1998 and 2017. The earthworks occupy an area of circa 6.5 hectares on the east side of the River Yealm. They do not correspond with any pit, ditch or mound features on the available 19th and 20th century historic maps, which show this area as comprising woodland. Transcription of these earthworks was carried out primarily using Simple Local Relief and Positive Openess lidar visualisations. Given their complexity and in places subtle nature, not all visible earthworks have been transcribed and an extent of area polygon has been used to define the approximate limit of the earthworks. Their character and form support the interpretation they represent the extractive pits, stream channels and associated spoil heaps of a possible medieval or post-medieval alluvial tin streamworks which had passed out of use by the mid to late 19th century, by which time the area had been given over to woodland. Water used in the washing and processing of the tin-ore was probably sourced from the River Yealm, via a series of leats. The earthworks are likely associated with a streamworks (MDV126820) recorded to the immediate south. Earthworks of numerous other streamworks have also been recorded in this area. Further investigation, such as a site investigation, is recommended to help define the extent and character of this possible streamworks.
