During the 1970s an architectural historical turn took place in Sweden. The 1970s also saw the breakthrough of a changing conceptualization of architectural history under the name of history of built environment. This article discuss how the historiography of history of built environment was produced and used, primarily focussing on the literature of the undergraduate programme in preservation of built environment, established in 1978. The aim of the article is to analyse in what way the historiographical content reflected and enacted the changing conceptualization of architectural history during this time.
