Walton Hall is said to have a bedroom door that reportedly opens to suddenly slam shut 30 seconds later. This curious phenomena has been attributed to an elderly lady who passed away in her bath in the 18th century, and longs to get back into her bedroom. The event is said to happen most often in June.
