It's believed the ghost of Anmer Hall is no other than its previous occupant, St Henry Walpole. The phantom has reportedly been seen on several occasions around the Sandringham estate.

A royal insider told UK's Express that St Henry Walpole's ghost has supposedly been seen haunting the royal gardens in Anmer Hall. His voice can reportedly even be heard along with the Norfolk winds.

Alan Murdie, chairman of the Ghost Club, assumed that having Walpole's ghost roaming Anmer Hall would be a good exposure to Prince George. He reportedly suggested that it would be good for the royal baby to grow up around ghosts in general. "Henry VIII did away with the monasteries, and to this day at the palace, the ghost of a monk appears on the terrace on Christmas Day," he said, adding that it's perhaps "the reason the royals prefer to spend the festive season at Sandringham."

Kate Middleton and Prince William were supposedly warned about the ghostly apparitions. However, the Duke and Duchess of Cambridge were not deterred and still renovated Anmer Hall, which has become their main home. After all, it was reportedly a gift to the royal couple from Queen Elizabeth II. "They were warned about it before they moved in and had a joke about it, but their attitude was: No old home would be complete without its ghost," the insider told Express exclusively.

According to Express, St Henry Walpole didn't die at the Sandringham estate. He reportedly died at Flamborough in Yorkshire but his ghost still returns to his old home. History claims he was persecuted for converting to Catholicism, which during the Elizabethan times was allegedly repressed by the Crown. He was captured en route to Norfolk and was taken to the London Tower to be tortured. He was later returned to Yorkshire in 1595 where he was believed to have been hanged, drawn and quartered. He was anointed as saint by the 1970s.

As for the Christmas celebrations in Anmer Hall, Daily Mail has all the details on Kate Middleton and Prince William's plans for their holiday at the Sandringham estate. There were no mention of any ghostly apparitions. It's also believed Queen Elizabeth II will be making an apperance at the festive celebration among other family guests.
