Summary

Sub-oval and irregularly shaped pits, cuttings and mounds, interpreted as medieval or post-medieval alluvial tin streamworks, are visible as earthworks on aerial photographs taken from 1946 onwards and on visualisations derived from lidar data captured between 1998 and 2017.

Sub-oval and irregularly shaped pits, cuttings and mounds are visible as earthworks on aerial photographs taken from 1946 onwards and on visualisations derived from lidar data captured between 1998 and 2017. The earthworks occupy an area of circa 5.4 hectares of floodplain along the western side of the River Plym. The earthworks do not correspond with any pit or mound features in this location on the mid-19th century Parish Tithe Map, or on later available historic maps. 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-19th century. Water used in the washing and processing of the tin-ore was probably sourced from the River Plym to the east, via a series of leats. The earthworks are not visible on other available aerial imagery other than in 1964 owing to dense tree cover. Further investigations, such as targeted trenching is recommended to help define the character of these earthworks. Earthworks of additional tin working sites have been recorded to the north and south.
