MSO12506 - Post-medieval surface workings and adits at Wheal Eliza (Monument)

Several 19th Century adits and signs of surface workings are seen as earthworks around Wheal Eliza mine (MSO6802). Around 50 metres upstream from the mine are 2 or possibly 3 adits surviving as linear depressions with upcast banks on each side. The west adit is approximately 1.25 metres deep with large banks on each side for about 15 metres, then a slight depression runs up the hill possobly covered by a field wall to the north. The other river bank adits are similar. There are at least two others higher up the hillside and a circular rock-cut feature about 1.5 metres in diameter immiediately northeast of the main shaft (MSO12503). The rock outcrops northwest of Wheal Eliza cottage (MSO12505) also show signs of surface workings. [1-3]
