A large selection from Unconscious Places , the German photographer Thomas Struth’s epic series of urban views, featured prominently at the 2012 Venice Biennale, curated by the renowned architect David Chipperfield under the title Common Ground. Facilitated in part by Chipperfield’s friendship with Struth, the display at Venice was also intended to resonate with the theme of common ground. While, for Chipperfield, the term was meant primarily to suggest the discipline’s shared knowledge, it was also taken to connote a shared interest in the open, collective urban realm.
