Sightseeing with a twist. This half-true-crime and half-historic-sites tour visits every historic site in Revolutionary Philadelphia not covered in our 8 pm Dark Philly Histories tour. Betsy Ross House, Christ Church, Elfreth’s Alley, and Benjamin Franklin’s Grave, together with tales of serial slayings and psychopathic killers keep it interesting. Your tour guide has a Master’s Degree in History or is a professor. Subscribe to Grim Philly’s podcast for even more in-depth and well-researched true-crime topics in and outside of Philadelphia with detectives, psychologists, and other professionals
