Mysterious hidden door finally opened in Nottingham's most haunted building The door was found sealed shut behind a fake wall. A mysterious hidden door sealed shut behind a fake wall in Nottingham's most haunted building has been opened for the first time. Haunted Museum owners Marie and Steve Wesson discovered the venue's only metal door under a layer of plasterboard when they acquired the old Mapperley picturehouse last year. Welded shut, it was found in the one-time projectionist's emergency exit chute with plugs and electrics fitted over it. Fearful of what they may find behind it and aware of sinister rumours surrounding its past, the couple left it locked for more than a year but yesterday (August 15) along with a group of seven paranormal enthusiasts they finally cracked it open. Inside, Marie claims they found a five-pointed pentagram star made from charcoal, a grubby old teddy bear and a collection of white candles burnt to their stubs. A five-point satanic star was found behind a hidden door behind a stud wall It was a shock to the 44-year-old, who'd just expected to find a brick wall on the other side of the door. "I couldn't believe what I was seeing," says Marie, who recreated a ghostly groping for an American TV show. "We're paranormal investigators not satanists so were are going to have to get on it to find out as much as we can about it." She's convinced however, that spooky things have already been going on. "During investigations [at the museum, recently ranked the 29th most haunted place in the UK by supernatural website higgypop.com], we've had voice recordings of someone saying 'don't open the door' and 'don't open the door' with a sinister laugh after. The owners found a hidden door behind a stud wall "It put me off [opening it]," says Marie, who also claims to have heard scratching coming from inside the sealed room on numerous occasions. Now opened, staff will be putting a Perspex sheet across the doorway so visitors can see but not touch the creepy findings. "Since we've opened it, a few people have complained of having headaches. My daughter, who never gets headaches, got a really bad pressure behind her eyes," says Marie, who isn't bothered by sceptics or non-believers. .
