This lecture course surveys modern architecture, urban ism and allied arts from the end of the 18th century to the present. The aim is to present a historical understanding of the period, and to develop a meaningful framework to assess contemporary issues in architecture. We will discuss architecture in relation to major paradigms of thought, artistic explorations, and social transformations. Since the paradigmatic shift between 1960’s and 1980’s which closed the modern times and opened a more pluralistic, postmodern world where we still live in, also the historiography of the modern architecture underwent a major transformation. Instead of an enthusiastic glorification of all of the modern architectural and urbanization praxis -as it was before and sometimes still is-, a critical review of dogmatic and shortcoming intentions of modernity will be the aim of the lectures. But this critical attitude will also cover its aftermath till the recently executed buildings and urbanization issues.
