Betsy Ross House (18th-century rowhouse with disputed association)

The three-story red brick rowhouse at 239 Arch Street dates to the 18th century and has been preserved and interpreted as the home where Betsy Ross lived in the 1770s. The association of the house with Ross's sewing of the first American flag is historically disputed among scholars, though the site has long been promoted as tied to that story and has been a museum since the late 19th century. The building's colonial-era construction and subsequent 19th- and 20th-century restorations reflect changing historic preservation practices.
