Oxford Castle and Prison has dominated Oxford’s skyline for almost 1,000 years, with the historic complex associated with warfare, executions, escape attempts and imprisonment.
The Oxfordshire landmark is also renowned for reports of ghostly activity, particularly around Halloween.
The Norman structure was established shortly after the conquest of England in 1066 and became an important part of Oxford’s medieval history.
Its role changed over time as the former stronghold developed into a prison for people convicted of offences ranging from theft to murder.
Although much of the site now operates as a visitor attraction, accounts of hauntings continue to circulate among visitors.
Tales include unexplained sounds, sudden cold areas and apparitions associated with former inmates.
Mary Blandy, a woman from Henley, is among the castle’s most frequently mentioned figures.
In 1752, she was convicted of poisoning her father with arsenic after he objected to her plans to marry.
Her trial was held at the Oxford Assizes at the Old County Hall in New Road.
She was subsequently detained at Oxford Castle before being taken to be executed.
Blandy is most commonly associated with the site’s haunting stories.
According to local legend, her spirit remains within the castle and former prison buildings.
Some people have reported seeing a female figure dressed in 18th-century clothing, while guides and paranormal enthusiasts have long recounted incidents involving strange noises and abrupt changes in temperature.
Empress Matilda is another figure said to haunt the castle.
During the civil war known as the Anarchy, King Stephen’s forces surrounded Matilda inside Oxford Castle in 1142.
Historical accounts describe her escape during winter, when she crossed snow-covered ground in white clothing.
Stories also connect her apparition with St George’s Tower and the old battlements.
The complex’s annual Ghost Fest runs from October 23 to 31.
Its Spooky Tours offer nighttime access behind bars and to prison areas that are normally closed to the public, accompanied by accounts of local legends.
A Potion Making Experience for families and younger children takes place in the medieval crypt beneath the castle.
Participants follow clues, make a potion and create a wand to take home.
