In his widely acclaimed The Pennsylvania Barn, Robert Ensminger provided the first comprehensive study of an important piece of American vernacular architecture—the forebay bank barn, better known as the Pennsylvania barn or the Pennsylvania German barn. Now, in this revised edition, Ensminger has continued his diligent fieldwork and archival research into the origins, evolution, and distribution in North America of this significant agricultural structure. Including an entire chapter of new material, 85 new illustrations, and updates to previous chapters, this edition of Ensminger's classic work will appeal to students and scholars in cultural and historical geography, folklore and vernacular architectural history, and American studies, as well as to general readers.
