Deconstructionism is a 20th century philosophical movement initiated by Jacques Derrida that questions assumptions about certainty, identity, and truth. Deconstructivism in architecture emerged in the 1980s, drawing inspiration from postmodernism and contemporary art movements. It is characterized by fragmentation, distortion, and rejection of ornamentation. Daniel Libeskind is a prominent deconstructivist architect known for projects like the Jewish Museum Berlin, which uses its zigzag shape and voids to symbolize the disappearance and absence of Jewish culture in Berlin during the Holocaust.
