This commercial building is unique because it showcases the city’s only surviving example of a cast-iron storefront. The first-floor façade is cast-iron.The primary structure is brick. A maker’s mark on the façade identifies the iron foundry: Royer Brothers of Philadelphia.
Historic cast-iron buildings are landmarks in Manhattan’s Soho district and in Philadelphia’s Old Town.
The building was constructed in 1873 as a grocery store and wholesale grocery warehouse for Miller and Hartman, the area’s first grocery wholesaler.
