A photographer captured an image of what appears to be a ghost standing behind a window in the interior of the Tantallon Castle, in Scotland.

The photo, taken by Christopher Aitchison in May 2008, shows a "person" wearing an old-style greenish ruff around the neck, according to CNN. The castle is located along the Scottish coast, east of Edimburg.

The photographer says he cannot explain the photo and insists he did not tamper it.

"Staff have verified that there were no sinister dummies in period costume or historical reenactments going on that day at the castle. I did not notice any nice old ladies wearing ruffs walking around the stairs!" he said according to CNN.

The image was published by a professor of Psychology from the University of Hertfordshire who also studies the paranormal.
