THEORY
ABSTRACT -

This essay critically examines the continuing relevance of the archipelago city – as theorized by Oswald Mathias Ungers in the 1970s – as a morphological and conceptual framework for understanding contemporary urban conditions. Originally developed in response to the fragmentation and depopulation of post-war Berlin, the archipelago city posits a model of urban organization based on autonomous, differentiated spatial units or ‘islands’ within a continuous green matrix. The essay situates this model within a broader theoretical lineage, drawing connections with Colin Rowe’s “collage city,” Aldo Rossi’s theories of typology and memory, and Rem Koolhaas’s concept of “junkspace.” Through morphological and compositional analysis, it explores how Ungers’ vision has been reinterpreted in projects from the 1990s to the present, including proposals by Franco Purini and Laura Thermes. These case studies highlight the adaptability of the archipelago paradigm in the contexts of accelerated urbanization, formal heterogeneity, and socio-political complexity. Finally, the essay reflects on the limitations and potentials of the model in an age marked by globalized urban development, the rise of the zone and the increasing marginalization of architectural agency.
