Eden-Petteril-Caldew Transect Air Photo and Lidar Mapping Project

This project will undertake archaeological air photo and lidar mapping, analysis and recording for an area south of Carlisle. The transect crosses three river valleys: the Eden, Petteril and Cardew.

The adjoining Hadrian’s Wall and Cumbrian Terrestrial Minerals Resource (CTMR) NMP projects revealed prehistoric enclosures, Iron Age and/or Roman farmsteads and fields systems and later features. Some of these monuments survive as earthworks and others were seen as cropmarks. It is likely that this project area has similar potential. It is crucial to have these monuments documented and on a map so that when schemes such as Carlisle’s planned Southern Relief Road are implemented the archaeologists and planners can take appropriate action on the ground.

New light on an old discovery

In 1789 Hayman Rooke reported to the Lord Bishop of Carlisle on a number of antiquities he had discovered including Castlesteads Camp near Stockdalewath. The enclosure was ‘re-discovered’ as cropmarks by aerial photographers in the 1970s. The central area was excavated in 1979. These investigations indicated that the more curving outer enclosure was earlier than the near-square inner enclosure. The inner enclosure contained cobbled surfaces and was tentatively interpreted as a Roman farmstead.

Reportedly, some time after Hayman Rooke’s visit, the ditches of the Castlesteads Camp were deliberately filled in with clay. This may have coincided with the laying out of the hedged fields shown on the photo above when Dalston parish was enclosed in the early 19th century. The cropmarks of this enclosure are probably so bold because of this clay filling. Interestingly the lidar imagery indicates that these ditches have not been completely levelled and also shows two hollow ways leading south-west from each enclosure down towards the River Roe near Stockdalewath.

Current programme of work

The project is being carried out by Alison Deegan and is due to run until March 2017. It forms part of the Historic England Action Plan and is funded by Heritage Protection Commissions (6949).

Work on the north-west quarter (nearest Carlisle) is complete and the data has been passed to the Cumbria Historic Environment Team. The south-west quarter is near complete and will be delivered in early 2016.
