This paper argues that Poundbury is a brick-and-mortar embodiment of the postwar paradox: an almost religious devotion to scientism and to “the future,” while at the same time grasping for the comforts of an imagined past. Perhaps this is why visitors to the town, even those who praise the place, describe it as “strange,” “like a movie set.” It is not so much “simulacra and simulation” as it is an uneasy negotiation, an effort to find a way to live in a period former AHA President J.R. McNeill describes as “something new under the sun.” To understand Poundbury requires understanding the relentless push and pull of countervailing forces that pit calls for perpetual growth against demands for sustainability, a consumerist devotion to individualism against a need for belonging, a celebration of the new against the comforts of a past defined by selective remembering and forgetting. The paper argues that if we want to understand nostalgia, we cannot remove it from a complex post-World War II project of perpetual renegotiation and imagining.
