Artefacts from what's thought to be the English Civil war have been unearthed at Auckland Castle. Archaeologists from Durham University have been excavating the site which will be open to the public at the end of the month.
The Auckland Castle Trust hopes to uncover 900 years of history.
After 10 days of digging in Bishop Auckland, remains of a building have been laid bare in a trench on an area close to the castle's Scotland Wing.
Auckland Castle's head curator, Dr Chris Ferguson, says the volume of debris is a 'puzzle and could suggest a very dramatic end' to what looks to be a substantial structure.
