Mary Capp Green Hall — Lebanon Valley College's resident ghost

Mary Capp Green residence hall at Lebanon Valley College in Annville Township, Pennsylvania, is one of the campus's most storied buildings due to its long history of alleged paranormal activity. Students living in the hall have reported hearing footsteps in the hallway when no one is visible, doors opening and closing on their own, and personal belongings being moved from one location to another. The most commonly reported phenomenon is the sensation of being watched while alone in a room, accompanied by a sudden drop in temperature. Some students have described seeing a shadowy figure standing in their doorway at night, only for it to dissolve when they turn on the lights. The identity of the ghost is disputed — some students believe it is a former resident who died on campus, while others attribute the activity to a Civil War-era spirit, as the college was founded in 1866 and the region saw significant military activity during the war. The residence hall has been the subject of several student-organized paranormal investigations, some of which claim to have captured anomalous audio recordings. Lebanon Valley College's ghost stories are a beloved part of campus culture, with new students often hearing about Mary Capp Green's ghost during orientation week.
