Summary

An irregularly shaped pit is visible as an earthwork on visualisations derived from lidar data captured in 2013 and on digital images derived from aerial photographs taken in 2019. It is interpreted as a quarry of mid-20th century date which probably truncates an earlier, post-medieval or 19th century quarry shown in this location on historic mapping.

A large irregularly shaped pit, circa 165m long by 40m wide, is visible as an earthwork on visualisations derived from lidar data captured in 2013 and on digital images derived from aerial photographs taken in 2019.
An earthwork labelled as ‘Old Quarry’ is shown at the eastern extent of this pit on the late 19th century First Edition Ordnance Survey map and on the early 20th century Second Edition Ordnance Survey map where it is labelled as ‘Quarry’. An additional earthwork labelled as ‘Old Quarry’ is shown in proximity to the west on the Second Edition map but is beyond the extent of the pit. The pit does closely correspond with an elongated earthwork feature shown on the 1953-1969 Ordnance Survey National Grid map.
The earthwork is therefore interpreted as a later phase of quarrying of probable mid-20th century date which has truncated an earlier, post-medieval or 19th century quarry (MDV36155).
