About this lecture:
The evolution of barn architecture tells the story of New Hampshire agriculture. Barns changed from the early English style, to Yankee style, to gambrel and then pole barns to accommodate the changing agriculture. This presentation will be a chronological walk through time, with photo illustrations of barns around the state that are examples of these eras of agricultural history.
