Two women in their 80s have denied damaging property, after the glass around the Magna Carta at the British Library in London was attacked.
Reverend Sue Parfitt, 82, and Judith Bruce, 85, each pleaded not guilty to a charge of damaging property, when they appeared in court in the city.
The Just Stop Oil supporters are accused of damaging the protective casing surrounding the historic document, which belongs to and is kept at the British Library, on 10 May.
Two protesters targeted the casing with a hammer and chisel before gluing themselves to the display.
Ms Parfitt, with an address in Bristol, and Ms Bruce, from Swansea, were given conditional bail at Wood Green Crown Court.
Their trial, which is expected to last four days, has been set for 13 January 2026.
The British Library said at the time of the incident that its security team "intervened to prevent further damage to the case, which was minimal" and the Magna Carta was "undamaged".
The document is regarded as one of the most important legal documents in the history of democracy.
It was agreed on 15 June 1215 and set out the laws that citizens, including the king of England, had to follow for the first time.
