What happens when an institution outgrows its container? In 2000, the Wadsworth Atheneum Museum of Art announced an expansion project that would consolidate its five existing buildings. By 2003, the plan had been abandoned due to its financial reach. This article explores the legacy of this unrealised project and the possible unconscious dynamics at play that led to this outcome. It also demonstrates the way irrational forces influence the development of the built environment, as well as the way architecture is used to contain anxiety associated with periods of organisational and societal change. I argue that this project's legacy endures as an under-explored and valuable case study illuminating the complex intersection of social systems, leadership, global architecture, urban development, and shifting understandings of the role of art institutions at the dawn of the new millennium.
