Gettysburg is believed by many to be the most haunted city in America. On July 1, 1863 150,000 soldiers descended on this small town in what would become the most devastating battle of the American Civil War. After the fighting ended a house on Cemetery Hill was repurposed as an orphanage for children who lost their parents to the fighting. This building has been named by the Travel Channel as the Most Terrifying Building in America and tonight we are going to search for paranormal activity inside it's haunted walls.
