Built in 1810, the Farnsworth House Inn served as a Confederate stronghold during the Battle of Gettysburg. Confederate sharpshooters fired from its attic windows, raining bullets onto Union soldiers below; over 100 bullet holes still mark the brick walls. Today, the inn is considered one of Gettysburg’s most haunted locations. Guests and staff report heavy footsteps in the attic, doors opening on their own, and the apparition of a little boy believed to be “Jeremy,” a spirit said to play tricks on visitors. Paranormal tours often highlight the house’s Civil War history and its enduring ghostly residents, making it a staple stop for investigators and tourists alike.
