Generally the Ancient universities, for obvious reasons, if you believe in that sort of stuff.
Apparently York is the one of the most haunted cities in the world, and although the city is a little bit of a trek from the main York campus, maybe all the ghosts like to chill out there now and then?
Indeed. It is sometimes difficult enough to get some work done or get a good night's sleep with the noise students make in halls, least you be haunted by those annoying ghosts.
You've obviously failed to spot the tomb of William Elphinstone in the third picture.

This is William Elphinstone:

Whereas our graves contain symbols like this:
...Which are symbolic of the pirates who may have lived flourished in Mile End in the 1600s before 'the Golden Fryer' became Mile End's capital.
Oh yer, I really think the ghost of William Elphinstone with his Bishop action fighting hat would be much scarier than the ghost of all those pirates (and Abraham Fernandez Carvajal, the founder of the modern Anglo-Jewish community, Haman David Nieto, a Sephardic spiritual leader and the physician Dr. Fernando Mendes) and a lot of other Jewish people.
(Who btw was also the Dean of the Faculty of Arts at the University of Glasgow and studied there, so if he was a ghost, he'd probably be haunting Glasgow more- it being a nicer looking uni and all).
William Elphinstone is the founder of King's College, Aberdeen. Hence he is the founder of the University of Aberdeen. His tomb is in King's College. Hence his tomb is in the University of Aberdeen. Hence his ghost wonders the University of Aberdeen.
Lancaster, apparently accomodation rooms are haunted (things get thrown about by the ghosts), didn't St Andrews have a legend where an wizard got his heart taken by the devil and that's why one of the buildings is a circular in shape?
William Elphinstone is the founder of King's College, Aberdeen. Hence he is the founder of the University of Aberdeen. His tomb is in King's College. Hence his tomb is in the University of Aberdeen. Hence his ghost wonders the University of Aberdeen.
Did I really need to spell that out for you?
There's a picture for you incase you can't read.
I was merely pointing out that he spent more of his life studying and teaching at Glasgow:
...hence his ghost may be there.
But fair enough, as he is the founder of Aberdeen and his tomb is there, it probably would be more likely that he lurks at Aberdeen.
My point that QMUL is more haunted still stands though.
