Within Greyfriars Kirkyard in Edinburgh, Scotland, looms a grimly baroque mausoleum covered in centuries' worth of dirt and grime.
It's a stark contrast to the otherwise well-maintained grounds, which include a tombstone that inspired a Harry Potter villain and the statue of a dog who was said to have sat by his deceased master's grave for 14 years.
That decay is by design: The structure has been allowed to lapse into neglect out of respect for the victims of the man buried inside.
Centuries after his death, it’s said that his restless paranormal presence terrorizes those who visit the graveyard.
It's this ghost—and not the extensive grave robbing and body snatching that occurred there in the 19th century—that earned the kirkyard a reputation as the most haunted cemetery in Scotland.
