Wessex Archaeology was commissioned by Cornwall Council and Treveth Developments LLP, to undertake an archaeological evaluation covering 5.7 hectares centred on NGR 168974, 042073, at Tolgus, Redruth, Cornwall. The works were undertaken in order to further evaluate the archaeological potential of the site according to Condition 3 of planning permission PA12/09717 granted by Cornwall County Council for the demolition of farm buildings, and the erection of 370 dwellings, along with associated access and utility arrangements. The excavation of 16 Trenches, located numerous boundary features comprising ditches and hedgerows likely representing post-medieval Cornish Hedges. Backfill and debris material within Trench 16, is believed to relate to mining activity undertaken across the site in the 19th century. Within Trench 13 evidence of prehistoric activity was also identified. Occurrences of stone rubble throughout the ditch may be unexplained but is of note due to the finding of a similar dump of stone within the ring ditch excavated during earlier archaeological excavation. These prehistoric features indicate there may have been some activity in the area during this period. Finds typically comprised pottery sherds of post-medieval date, with prehistoric sherds located within ditches. The archaeological evaluation succeeded in locating a feature pre-dating the post-medieval activity known to have occurred across the development site. Most significantly a ditch likely to date from prehistory was located within Trench 13, toward the eastern site boundary. The remainder of features largely indicate a network of drainage ditches and/or field boundaries dating to the post-medieval period, as well as a possible trackway. Evidence of 19th century mining activity was also identified in the form of debris and backfill material within Trench 16.
