Join a tour of unconventional sightseeing off the beaten path. Experience the Betsy Ross House, Christ Church, Elfreth's Alley, Benjamin Franklin's Grave, and numerous historic sites in Old Philly. And enjoy tales of serial slayings and psychopathic killers such as the Corpse Collector, Frankfort Slasher, and H.H. Holmes. 2.5-hour walking tour led by college professors or history teachers and is not your typical Liberty Bell Tour!
