Elfreth's Alley (Oldest Residential Street)

This charming 300-year-old alley in Old City Philadelphia is lined with beautifully preserved 18th-century townhouses that paint a vivid picture of colonial residential life. Strolling through Elfreth's Alley feels like stepping back in time, with its intimate brick facades, gas lamps, and window boxes creating one of the most photographed streets in America. The street remains a functioning residential neighborhood where descendants of original families still live alongside museums and galleries.
