This dissertation, delving into the vastness of this global theme, focuses on the city of Buenos Aires as a microcosm whose urban fabric has been intertwined and transformed over the centuries by migratory flows.
Mobility, intrinsic to the human essence, has shaped human history and continues to challenge borders and barriers in every known dimension. This complex phenomenon, characterised by varied motives, diverse trajectories, and profound effects, requires an interdisciplinary approach to understand it, even if the focus lies on the urban and architectural plane.
The approach was made through different types of disciplinary written documents from the fields of architecture, urbanism and history, legal, literature, statistical data and graphic documents. Thus, the texts for each chapter on the city were composed, and also chronological lines of significant socio-political events, graphs and drawings such as plans and profiles that inform each chapter, delimited and defined by each dominant Flux, from its origin to the present day of Buenos Aires.
Buenos Aires was idealised and built as a European city in the heart of the Pampean plain, originally inhabited by native ethnic groups, emerges as a living testimony to the diversity of human flows that have shaped its urban, cultural and identity landscape. From its foundation in 1580 to the present day, the city has been influenced by migratory movements, including Spanish settlers, overseas immigrants, particularly the mass European ones between 1880 and 1914, people from neighbouring countries and even the departure of the local population. This chronological study analyses the impact of these flows on the formation and metamorphosis of the city, highlighting the vital interconnection between human movements and urban evolution, ending in contemporary times, where it faces the challenges arising from emigration. The city, marked by uncontrolled growth and social segregation, reflects a complex and constantly changing reality.
