Haussmannization refers to the extensive urban renovation of Paris during the mid-19th century, led by Georges-Eugène Haussmann, the Prefect of the Seine. This transformation aimed to modernize the city by creating wide boulevards, improving sanitation, and enhancing public spaces. The project also involved the demolition of overcrowded neighborhoods and the construction of new buildings in a uniform architectural style. The changes made during Haussmannization significantly altered the city's layout and infrastructure. New parks, squares, and improved transportation systems were introduced, making Paris more accessible and aesthetically pleasing. This urban planning model influenced many cities worldwide, promoting similar modernization efforts.
