HER Number:MDV130425
Name:Extractive pit at Grenofen, Whitchurch

Summary

A circular pit surrounded by an irregularly shaped bank are visible as earthworks on visualisations derived from lidar data captured in 2013 and 2016 and as dark and pale cropmarks on digital images derived from aerial photographs taken in 2018. They are interpreted as a possible post-medieval or 19th century extractive pit and spoil heap that had passed out of use by the mid to late-19th century.

A circular shaped pit, 15m diameter, surrounded by a low irregularly shaped bank, circa 62 metres across, are visible as earthworks on visualisations derived from lidar data captured between 1998 and 2017 and as dark and pale cropmarks on digital images derived from aerial photographs taken in 2018.
The visible earthworks do not correspond with any pit or bank features depicted in this location on the mid-19th century Parish Tithe Map, or on later available historic maps. It is therefore interpreted as a possible post-medieval or early 19th century extractive pit and plough-spread spoil heap that had probably passed out of use by the mid to late 19th century.
