This historic inn was once Gerhart's Tavern. Gerhart's is famous for hiding the Liberty Bell, and as a station on the Underground Railroad. See, for ex., https://www.risingsuninn.net/about and https://www.risingsuninn.net/story-tremont. Reportedly, during Prohibition it hid a tank of liquor and it is haunted by "Scary Mary."
