Hampshire Downland National Mapping Programme project
The mapping covered some 403 square kilometres of chalk downland bordered by Winchester, Andover and Basingstoke. To the south and west, the project bordered areas previously mapped for the Hampshire South Downs and Hampshire ALSF projects. The downland west of the Test Valley was excluded as it had been mapped for the Danebury Environs Project (Palmer 1984).
The project, undertaken to NMP standards, was carried out by Cornwall Council in partnership with Hampshire County Council. Mapping and recording was carried out between September 2010 and April 2013. The project was funded by English Heritage through the Historic Environment Enabling Programme (HEEP), now Heritage Protection Commissions (HPC).
The threatened landscape
The Hampshire Downs extend across central parts of Hampshire, and form part of the broad belt of chalk running across southern England, linking Salisbury Plain to the South Downs. Today the downland is a largely open landscape characterised by large fields and intensive arable production.
The Hampshire Downs possess a remarkably rich archaeological resource, much of which has been reduced or levelled by repeated ploughing. This continuing agricultural threat to the extensive below-ground archaeological remains meant that there was a need for up-to-date mapping to NMP standards, using both historic and recent aerial photographs.
The value of historic aerial photographs can be demonstrated by the image below taken on the 21-JUN-1924 during one of the flights for OGS Crawford and Alexander Keiller’s publication Wessex from the Air.
The revealed landscape
The richness of the cultural landscape of the Hampshire Downlands has been emphasized by the large number of archaeological sites mapped and recorded by the project. 3,096 sites were identified on the aerial photographs, of which 2,103 – 68% – were previously unrecorded. These covered a wide range of site types, and spanned all periods from the Neolithic to the 20th century, demonstrating both the great complexity and intensity of historic use of the landscape within the project area.
86% of the mapped sites had been levelled, and were recorded as cropmarks or soilmarks, reflecting the long history of intensive agriculture in the region. Only 194 (6.5%) of sites still possessed some degree of above-ground survival as earthworks.
This enhanced awareness of the archaeological resource will aid management of the area’s historic environment on a site-specific as well as strategic level. By looking in detail at the cropmarks, NMP mapping will help define those parts of the Hampshire Downs most sensitive to threats from continued ploughing.
