Notre Dame Convent School in Northampton is home to a rather unusual ghostly presence. A former teacher at the school, known only as 'the Nun', is said to haunt a hall that was built after her death. What's fascinating about this apparition is that she's often seen walking knee-deep through the hall, as if the floor doesn't exist for her. It's a pretty bizarre sight, and one that's been reported by numerous people over the years.

The history of Notre Dame Convent School dates back to the 19th century, when it was established by a Catholic order of nuns. The school has undergone several changes and expansions since then, including the construction of the hall where the Nun is said to appear. According to reports, the Nun was a teacher at the school who died sometime in the past, but her spirit hasn't rested. Instead, she's doomed to relive her daily routine, walking through the hall as if she's on her way to class. Some people believe that the Nun's presence may be connected to the school's history, or perhaps she's a manifestation of the school's Catholic heritage.
