A Saxon skeleton believed to be a king or bishop has been discovered in Lincoln Castle.
The Saxon skeleton was in a stone sarcophagus believed to date from about AD900.
Its sarcophagus has not yet been opened but an endoscopy revealed the remains were buried alongside other objects, such as gold.
Mary Powell, from Lincoln Castle, said: "We think it's somebody terribly important, possibly a bishop or a Saxon king.
"At the moment, we can see the side of the coffin, but not the lid. It's going to be incredibly challenging to get it out, so we are being very careful.
"There is a danger it could disintegrate because of the change in environmental conditions.
