Montjuïc is a long flat-topped hill overlooking the harbour of Barcelona from the southeast border of the city. From 1915 onwards it underwent a profound transformation turning it into the site of the 1929 International Exhibition. Aurelio Castro Varela delves into this turning point, examining the aesthetic role of infrastructures in delivering pleasure on the hill before and during the dazzling, monumental display that characterized the event. He elaborates on two distinct regimes of pleasure by theorising their material forms as functional to and expressive of specific ways of having fun. Thus, such enquiry concerns the ambient conditions, sensorial landscapes and architectural elements through which pleasure took shape in Montjuïc from the mid-nineteenth century to 1936.
