Elfreth's Alley (Elfreth's Alley Museum)

Elfreth's Alley, with the Elfreth's Alley Museum at 126 Elfreth's Alley, is often described as the oldest continuously inhabited residential street in the United States, with houses dating back to the early 18th century. Its narrow cobblestone street and preserved row of historic homes are a popular subject for photography and heritage tourism, and images of the alley frequently circulate online. The museum offers guided tours and exhibits about the alley's residents and history.
