Boulevards, sewers, parks; axial vistas
Birth of modern infrastructure-driven planning
Under Napoleon III, Baron Haussmann remade Paris between 1853 and 1870 by cutting wide, straight boulevards through the dense medieval fabric, standardizing building facades, and installing modern sewers, water mains, parks, and rail termini — a vast, coordinated surgery of the existing city.
Haussmann's Paris is the defining act of 19th-century urban modernization, simultaneously a triumph of infrastructure and public health and a tool of social control and displacement. 'Haussmannization' became shorthand for the modern remaking of the city.
Executed 1853-1870 under Napoleon III with Haussmann as Prefect of the Seine; Haussmann was dismissed in 1870 but the works were largely completed and define central Paris today.
Critics argue the renovations displaced the working class to the periphery and served military and political control as much as public health, at enormous and partly opaque financial cost.
