Organised crime, political corruption and incompetence have left Italy with a disproportionate number of unfinished public works. Two architecture collectives, Alterazioni Video and Fosbury Architecture, advance the provocative theory that the phenomenon is not an accumulation of wrong-headed political choices but an Italian style. They map these “ghost” structures in a new book based on a decade’s worth of research, Incompiuto: The Birth of a Style, published in Italian and English by Humboldt Books, with contributions from theorists including Robert Storr, Marc Augé and Salvatore Settis. The survey of 696 unfinished projects across Italy reveals that they are much more prevalent in the South, with Sicily leading the way (163), followed by Sardinia (71), Puglia (69) and Calabria (58). Here is the Barche viaduct in Bomba, Abruzzo.
