Cornwall County Council Historic Environment Service interpreted and mapped the archaeology of the whole county, including the Isles of Scilly, from aerial photographs. The project transformed the amount of information known and the way it can be accessed by archaeologists and the general public. Historic and prehistoric sites and landscapes can be viewed interactively on the Cornwall Historic Environment Record Geographical Information System (GIS) and an overview is given on a special website.
A rich and varied heritage
Cornwall has a rich and varied archaeological heritage reflected in the wide range of sites mapped during the NMP project. A striking aspect of Cornwall’s historic landscape is the extraordinary legacy of its tin and copper mining industries. The value of NMP interpretation and mapping of early workings is that many of these features do not appear on any other maps. This data was a key source of information leading to the inscription of the Cornwall and West Devon Mining Landscape as a World Heritage Site in 2006.
Archaeologists in Cornwall are fortunate that in the uplands, the surviving remains are easily seen. On Bodmin Moor, for example, there are prehistoric settlements as well as abandoned medieval hamlets.
Away from the moors, in the farming heartland, many archaeological features have been levelled by ploughing. In some cases below-ground remains do survive and in certain dry summers these remains can be seen from the air as cropmarks.
The defence of Cornwall
Leaping forward in time, many of Cornwall’s wartime defences are visible on RAF aerial photographs taken during the 1940s. By mapping individual features, such as pill boxes, anti-tank ditches and anti-aircraft batteries, a picture can be built up of the complete defensive networks protecting the county’s key strategic locations.
For example Carkeel Anti-Aircraft battery is a fine example of a heavy anti-aircraft battery near the River Tamar which forms the county border with Devon. Ironically, although it is sited in Cornwall, this battery formed part of the defensive ring around Plymouth. Batteries like this worked to put up a barrage of fire to force bombers to fly higher, thereby reducing their accuracy.
The downside of this, of course, is that wayward bombs often fell onto residential areas. During the Plymouth blitz in the spring of 1941, the Cornish towns of Torpoint and Saltash, a few miles south of this battery, sustained severe damage.
