Airy area of northwest Philadelphia from Sharpnack Street to the old Ft. Washington branch of the Pennsylvania Railroad. It contains 264 buildings, mostly two-story brick and stone structures of mixed residential, commercial and institutional use.","why_significant":"The nomination argues the extension shares the existing district's significance in architecture and commerce, since Germantown Avenue has long served as a commercial artery and a mix of styles from the Colonial period to the 1930s is represented. It adds education as an area of significance, citing several historically important schools and seminary campuses within the extension.","narrative":"Along Germantown Avenue in Mt. Airy, northwest Philadelphia, this extension of the Colonial Germantown Historic District contains 264 buildings, most of them two-story brick or stone structures. The earliest known building dates to 1740 and the most recent to 1984. The avenue began as an Indian path and became a turnpike in 1801, and its shops, inns and taverns made it a commercial center for more than two centuries. Mid-19th-century storefronts survive at 6536-6538 Germantown Avenue, built between 1857 and 1861. The area also holds a notable group of educational institutions, including the Lutheran Theological Seminary, the Lutheran Home, and the Pennsylvania School for the Deaf, whose stone Victorian Gothic buildings were designed by Cope & Stewardson and the Wilson Brothers. Architects produced buildings across most major styles in America before 1930, and the Colonial Revival designs drew on local stone and side-gabled forms. The nomination treats the district's variety of styles as part of its value.","period_of_significance":"1744-1940","architect_builder":"Cope & Stewardson; George T.
