Case Study:
Sonning Cropmark Complex
In Autumn 2012 TVAS undertook a detailed geophysical survey of an important
prehistoric cropmark complex at Sonning, near Reading in Berkshire. Aerial
photographs had revealed the presence of a Neolithic cursus monument along
with a ring ditch and several rectangular enclosures, one of which is a Neolithic
mortuary enclosure. However, because of the nature of the cropmarks, the position
and form of the western end of the cursus and therefore its complete length was
unknown. The complex forms a Scheduled Monument and consent was granted
by English Heritage to survey the site in an effort to locate the missing detail and
reveal any new features. The results were a great success. Not only were we
able to locate a western end to the cursus but the survey also identified another
probable rectangular enclosure and several linear features.
