A woman who was bludgeoned to death in her own home suffered more than 50 injuries to her head and arms, a court heard.
Judith Richardson, 77, was attacked during an alleged robbery at her terraced house in Hexham last August.
Graeme Jarman, 48, from Consett, who is appearing at Newcastle Crown Court, denies her murder.
Pathologist Dr Jennifer Bolton told the court Miss Richardson had died from "at least 30" blows to the head from a blunt object.
She suffered 34 separate bruises and cuts to her head, and a fractured skull.
The court heard she had tried to defend herself using both her arms - which were also badly bruised.
The jury was shown a computerised model of her injuries, which Dr Boulton said were consistent with blows from a hammer found close to the murder scene.
The trial continues.
