    Have there been any reports of paranormal incidents at this location? I was there a year ago and had to leave immediately, due to unexplained feelings I experienced in specifically one spot near the “Children’s Garden” which is now part of the Holocaust Museum. I’ve been trying to find out if something specific happened there to cause a haunting.


    1. I’m not sure whether or not it is. Thank you for asking. I’ll let you know if I find any information regarding the paranormal. Apologies for the late response.
