The photo exhibition ’Suprastructure’ was first displayed at Museum Gustavianum in Uppsala between 17 November 2012 and 5 March 2013. It was digitally published in March 2013 as part of a research project entitled ‘Infrastructure as Divination: Urban Life in the Postcolony,’ financed by the Swedish Research Council. The scholars behind the exhibition, Ulrika and Erik Trovalla, are researchers in cultural anthropology and ethnology. They are based at the Nordic Africa Institute, Uppsala, and Uppsala University. Drawing on their photographs from the million city Jos in central Nigeria, they here give a glimpse of their research into the meanings of infrastructure in everyday life.
