We’re always thrilled to learn about famous row houses. The Betsy Ross house in Philadelphia is pretty well known and a regular stop on the tours. Although it stands alone today, it was attached at one point. The entry has been re-fabricated and may or may not be what the home originally had, but is typical of the intact row homes in the area from the period. The house was built around 1740, in the Pennsylvania colonial style, or a localized version of Georgian style that was typical of the time.
