This is one of the very first locations I went to on my paranormal journey.

History:
In the 13th century a large silver disc was seen in the sky above the abbey. It is chronicled in the William of Newburgh reports that the abbot was about to say grace when one of the monks ran in announcing 'there is a great portent outside'. According to manuscripts it was frightening and the greatest terror.
