Elfreth's Alley - often cited as the oldest continuously inhabited residential street in the United States

Elfreth's Alley, a preserved row of 18th‑ and early 19th‑century houses, is widely cited as the oldest continuously inhabited residential street in the United States, with buildings dating from about 1702 onward. The Elfreth's Alley Museum at 124 Elfreth's Alley interprets the history of the alley, its former residents, and urban life in colonial and early American Philadelphia. The narrow cobblestone lane is a designated National Historic Landmark and a notable example of early American urban residential architecture.
