The Lightner Farmhouse in Gettysburg, used as a field hospital during the Civil War, is reportedly haunted by spirits of soldiers and displays phenomena ranging from harmless pranks to residual energy. The 18-acre property, including the main farmhouse, barn site, and former cookhouse, is said to be particularly active. During the Battle of Gettysburg, the Lightner Farmhouse was converted into a hospital for the Union Army's 1st Division of the 1st Corps. The original barn was used to treat common soldiers, while officers were taken inside the farmhouse. Some of the soldiers nursed back to health were later honored by having guest rooms named after them. Unfortunately, many soldiers who could not be saved were buried in unmarked graves on the farm's property. This tragic history is the foundation for the hauntings. Some spiritual activity inside the house is described as fun-loving and benign. Guests have reported door handles jiggling in the early morning hours, as if mischievous spirits are trying to wake them up. A guest once reported seeing the apparition of a soldier sitting in a chair in their room at night. Eerie residual energy lingers on the second floor, where guests have heard the sound of a body being dragged down the hallway. It is thought to be the sound of a patient who did not survive being removed from the house. The farm's 18 acres, including the location of the former barn and cooking quarters, are believed to be heavily haunted. Many people have reported seeing apparitions of soldiers walking the grounds, still seemingly going about their duties. One guest was reportedly awoken around 3 a.m. to the sound of a snare drum. Paranormal investigators have explored the property, reporting activity such as disembodied voices and hits on K2 electromagnetic field detectors.
