The Slaughter Pen at Gettysburg is described as a haunted location where visitors report seeing apparitions, hearing disembodied voices, and experiencing electronic equipment malfunctions, all attributed to the area's bloody history as a battlefield. It was a wooded area at the base of Round Top, where the ground was covered with the dead after fierce fighting, earning its grim name. Visitors have reported seeing apparitions, often described as shadowy figures or the ghostly forms of soldiers. Disembodied voices and sounds of battle have been recorded, even when no actual activity is present. Cameras and other electronic equipment are said to fail inexplicably in the area. Some accounts mention hearing mournful voices or feeling unseen presences.
