International Colloquium on 25 + 26.10.2022

Berlin has proposed to place the major listed ensembles of Berlin's reconstruction under the title "Karl-Marx-Allee and Interbau 1957. Architecture and Urbanism of Berlin's Postwar Modernism" on the German Tentative List of World Heritage Sites and subsequently then to propose them to UNESCO for inscription. The first attempt in 2014 was appreciated, but it was asked to be revised. A new application would then be made in the fall of 2021. The newly submitted proposal will be presented and discussed with external experts at the colloquium at Triennial of Modernism .
