Book excerpt: This photographic story of three dynamic neighborhoods in Philadelphia's twenty-first ward traces the evolution of each community as defined by its architecture. From the outstanding Tudor Historic District to elegant homes near Wissahickon Avenue, East Falls is a must-see neighborhood for connoisseurs of fine domestic architecture. Manayunk, once known as the Manchester of America, still retains its European hill town character, preserved in its worker homes, churches, and mills. Roxborough has its own unique architectural profile, with suburban residences of the Victorian era and the rural setting of Upper Roxborough. Historic Ridge Avenue is dotted with venerable structures from the eighteenth and nineteenth centuries. Brimming with nearly 500 full color photographs and archival images, and supplemented by selected biographies of the featured architects and firms, this book will charm history buffs, lovers of vintage architecture, and Philadelphia enthusiasts.
