This monograph has been published in connection with the MAXXI’s Premio Italia Contemporanea prize that Giorgio Andreotta Calò won in 2012 and was developed in collaboration with him focusing on his installation Prima Che Sia Notte. The work of Calò — performative and ephemeral — rests at the intersection of art and architecture. He intervenes on buildings and landscape, appropriating and transforming architecture and space into symbolic and aesthetic experiences. His most significant works include a series of walks that took him 1,600 miles through France, Spain, and Portugal, or 98km along the abandoned coastal train line in Lebanon, or the appropriation of the abandoned parliament building in Sarajevo which he illuminated from sunset to sunrise with an artificial light.
