Philadelphians have lived on Elfreth's Alley since 1702 - not the same ones, of course - making this America's oldest inhabited street.
Where is Elfreth's Alley?
There are thirty two houses on Elfreth's Alley located between North 2nd Street and North Front Street, in the block between Arch and Race Streets.
It is a public street so you can visit whenever you'd like, but please keep in mind these are people's homes.

The 18th century house at 124-126 Elfreth's Alley has been turned into museum to display a house renovated to Colonial-era times. Tour guides are available to discuss life of the residents through the years as well as tour the alley for the stories of the homes along the way.

Museum Hours: Friday & Saturday 12pm-5pm
The museum is closed in the winter. It will reopen in April 2015.
Admission: $5 for Museum Entrance and Alley Tour
A guidebook to the homes on the alley is available at the museum.
Who is Elfreth?
The alley is named after Jeremiah Elfreth, a silversmith in the area. This small alleyway was just a cart path and he lived and worked nearby on 2nd Street. He lived at 126 Elfreth Alley, which is now the home of Elfreth Alley Museum.
