Piercebridge

Also known as, or recorded in historical documents as; Carlbury

In the civil parish of High Coniscliffe.
In the historic county of Durham; County Palatinate of (Modern Authority of Durham, 1974 county of County Durham).

Butler suggests a low mound here is a potential castle site. I'm not certain as to what Butler is referring but I suspect, based on the sketch map in the article, he might mean a mound described as "Probable Bronze Age round barrow surviving as a plough-reduced earthwork. Slightly elongated mound, probably a large bowl barrow, measuring 38.5m in north to south diameter and 3m high and 42m in east to west diameter and 1.7m high, with no visible ditch" This seems a very unlikely castle site to me as it would be easier to build a castle within the Roman fort of Piercebridge where a settlement did exist and which was better sited to control the crossing.

This site has been described as a;
Timber Castle.
The confidence that this site is a medieval fortification or palace is Questionable.
Earthworks remains.

This site is a scheduled monument protected by law.
