Betsy Ross flag tradition at the Betsy Ross House

The Betsy Ross House at 239 Arch Street is traditionally identified as the place where upholsterer Betsy Ross sewed the first American flag in 1776 according to family accounts first publicized in the 19th century. The site is operated as a museum and historic house in Philadelphia's Old City. Historians and flag scholars dispute the documentary evidence for the specific claim that Ross designed or sewed the first official U.S. flag, and that dispute is part of the site's interpretive history.
