Summary of Aldo Rossi: Neo-Rationalism and Postmodernism

## Introduction Aldo Rossi and Urban Architecture explores the relationship between architecture as an object and the city as memory, typology, and collective space. This material focuses on Rossi's approach to the urban artifact, his participation in the Teatro del Mondo project, and his role in the concept of the Internationale BauAusstellung (IBA) 1984/87 in Berlin. The aim is to understand how Rossi theoretically and practically shaped urban space. ## Basic Concepts and Definitions > **Definition: Urban Artifact** — an element within urban space that possesses its own distinct identity and memory; it can be a building, a square, or an urban form that contributes to the city's collective memory. > **Definition: Urban Typology** — the systematic classification of urban structures according to recurring forms, functions, or historical patterns. > **Definition: Collective Memory** — the sum of a society's memories embodied in the physical elements of a city, which influence the identity and perception of a place. ## Aldo Rossi and Teatro del Mondo (1979) ### Context and Significance - Teatro del Mondo was a floating theatre created for the Venice Biennale, reflecting Rossi's 18th-century sensibility and his ability to translate historical character into a new form. - Rossi stated about the theatre that it is a place where architecture serves as a background, scenery, and a structure that can be calculated and transformed into specific materials and measurable elements that evoke a mood. ### Practical Example - Teatro del Mondo demonstrates how a historical style or memory can be concretized into a new, mobile, and functional structure. It's a case where architecture functions as "scenery" but also as a fully-fledged artifact within the urban experience. Did you know that Teatro del Mondo was perceived not only as an artistic object but also as a way to commemorate and revive Venice's historical identity in a modern context? ## Rossi and IBA 1984/87 in Berlin ### Political and Urban Context - IBA 1984/87 responded to the need for a new approach to urban renewal in West Berlin; it was an alternative to the massive modernist Miesian or totalitarian planning logic. - The project, led by Josef Paul Kleihues, adopted more authorial approaches to the renewal of urban structures. ### Rossi's Contribution and Theory - Rossi advocated a *fragmented*, *multi-site*, and *multi-phase* urban typology instead of a unified, universal plan. - In the article „Aspetti della tipologia residenziale a Berlino, 1960" in Casabella magazine, Rossi praised Berlin for its urban fabric, which supports smaller zones, urban artifacts, and layers of memory. ### Application in Practice: Projects in Berlin - Rossi realized constructions on Kochstrasse and Wilhelmstrasse and a project of urban villas on Rauchstrasse. These realizations allowed him to put theory into practice and place his artifacts into Berlin's „multi-layered collective memory“. ## Breakdown of Concepts: How Rossi Structures the City ### 1) Urban Zones and Fragmentation - Smaller zones mean greater diversity of functions and forms. - Fragmentation prevents the dominance of a single planning principle. ### 2) The Urban Artifact as a Repository of Memory - An artifact need not be monumental; it can be simple in form but significant for identity. ### 3) Typology as an Analytical Tool - Typology helps to recognize recurring forms and their relationship to historical context. ## Concept Comparison (Table) | Concept | Characteristics | Impact on the City | |---|---:|---| | Fragmentation | Division of the city into smaller units | Increased diversity, flexibility | | Urban artifact | Individual element with memory | Stronger place identity | | Typology | Classification of forms and functions | Tool for analysis and design | ## Practical Examples and Applications for Urban Design 1. Regeneration of Damaged Neighborhoods: dividing into smaller, thematic zones with their own identity. 2.
