Cadson Bury is an Iron Age hillfort about 2miles south-west of Callington, in Cornwall, England.
It is owned by the National Trust,[1] and it is scheduled monument.
The fort is sited in a commanding position on a steep hill, called Cadson Bury Down, above the River Lynher.
It is univallate, probably of the early Iron Age.[2] The oval enclosure, longest from north to south, is about 275m (902feet) long and 170m (560feet) wide, enclosing an area of about . The rampart is up to 2m (07feet) above the interior; the outer ditch is about 1.3m (04.3feet) deep on the east side, less visible elsewhere.[1] There are no traces of house platforms within the enclosure. There are two opposed inturned entrances on the east and west sides; the eastern entrance is clearly defined, the western entrance less so. Another entrance on the south may not be original.[1] [3]
