The Olympic Games 2024 were prepared years ago. Already the application procedures to prepare “un dossier” has to bring in lots of ideas and imagination what is desirable and feasible. Paris opted for a celebration of sustainability in a city proud of its medieval heritage and the Haussmann tradition of radical transformations of a city with large boulevards and representative buildings. From the “Arc de Triomphe” the major axes of communication between “arrondissements” become visible. 100 years ago the city had already been transformed according to this master plan. At that time sanitation of a city meant different things than today. The invasion of inner cities by Diesel-driven cars made life unhealthy again. Now, the Olympics gave reasons to restrict cars and lorries passing the inner city and the great boulevards. More tourists need more space and shall keep a much better memory of how pleasant Paris was during the Olympic Games. This could be a game changer for urban development in general. The proportion of pedestrians versus cars has to be shifted in favor of the walking population for many reasons. Tourists will flock to the city, if the overall and shopping experiences are great. Back to the future sounds crazy, but it has an interesting flavor to it for urban renewal and residents as well. (Image Paris 2024-8, b/w color filter applied, enlarge to see vasque)
