Philadelphia kept its 18th-century alley network — Elfreth’s, Cuthbert, Church. Three picks that use the colonial slots as cool cut-throughs.
Old City’s alleys were laid out for handcarts, which makes them nearly ideal pedestrian infrastructure three centuries later: ten feet wide, brick-walled, and shaded except for a thin noon stripe. Elfreth’s Alley gets the postcards, but Cuthbert, Church, and Philip run the same geometry without the crowds.
Society Hill adds the London plane canopy on its residential blocks — Delancey and Spruce hold full cover. These picks stitch alleys to canopy.
North on the churchyard’s brick path, then the alley itself — America’s oldest street, still its shadiest.
Through Washington Square’s plane canopy — the quietest of the five original squares.
Society Hill’s plane-tree tunnel, Second to Fifth. Cobbles, shutters, full canopy.
