Is England’s Belgrave Hall haunted? This surveillance footage from 1998 leaves some wondering.

“The security cameras at the back of the hall triggered off one night at about 4: 50 a.m.,” curator Stuart Warburton told BBC News. “Then suddenly … two figures appear on the film. The camera freezes for about five seconds and then the figures disappear. And then we have a mist that swirls along the top of the wall, which we cannot explain.”

Belgrave Hall, a Victorian museum in Leicester, has long had a ghostly reputation. Legend has it a former owner’s daughter haunts the 306-year-old residence, though no knows why. Many refer to her ghost as The White Lady. Other reports include eerie shadows, unexplained footsteps, and the smell of “old-fashioned cooking.” What do you think of the video?
