The oldest continuously residential street in the U.S., Elfreth's Alley celebrated its tercentenary in 2002. This small block offers a charming stroll past 33 tiny row houses built in the early 18th century by blacksmith Jeremiah Elfreth. Originally occupied by artisans and seamen, many today are private homes. The alley is also celebrated for its art galleries. Stop by the Mantua Maker's Museum House at No. 26 to see artifacts and exhibits that chronicle the street's past. Open Monday-Saturday 10 am-5 pm, Sunday noon-5 pm; closed Monday-Wednesday November-March. US$5 adults, US$1 children. Second Street (between Arch and Race streets), Philadelphia.
