Deconstructivism emerged in the late 1980s as a development of postmodern architecture influenced by deconstruction theory. It is characterized by fragmented and non-rectilinear shapes that create unpredictability and controlled chaos. Peter Eisenman was a prominent American architect known for works like the Memorial to the Murdered Jews of Europe that used disconcerting forms and angles to create an incomplete experience for viewers, reflecting his belief that parts in conflict contest the completeness of the whole.
