During Mark Twain's last visit to Hannibal in 1902, he addressed 300 members of Hannibal society from the magnificent stairway of Rockcliffe, then celebrated as one of the finest river estates in America. Rockcliffe's 30 rooms are now beautifully restored. Rockcliffe Mansion is now also on the National Historic Register.
