"Laurel Hill Cemetery offers a number of self-guided tours by foot or car. The office provides maps, but the best way to explore this 78-acre National Historic Landmark—the nation’s second oldest cemetery—is by downloading the app and selecting a tour from its list. Themes include art and architecture; pop culture and contemporary stories; and lore and legend. All tours last anywhere from 90 minutes to two hours. The cemetery is open seven days a week from morning until late afternoon." - Nancy DePalma
