The Sainte-Victoire mountain (France), major landmark of Aix-en-Provence area, has been a source of inspiration for many artists since the 15th century. I observe this mountain which is moving away, more and more, undergoing the effects of changing urban landscapes. Urban areas are home to more than half of the world's population, they play an important role as growth engines and provide opportunities for employment and education. They meet the changing needs and aspirations of their inhabitants. However, when the urbanisation is too rapid and poorly controlled, it leads to a severe deterioration in the quality of the urban environment and its peripheral rural areas. This phenomenon can be linked to construction standardisation and monotony as well as the disappearance of public space and excessive construction density. The uncontrolled expansion of cities is a real ecological threat to humanity, scientists believe that more than 70% of current CO2 emissions are related to the needs of cities. Yet "all over the world, we are adopting "Western" urban and architectural styles, which are resource-intensive and too often unsuited to local climatic conditions. The North American suburb has been exported around the world, with its model of individual car traffic," says Professor Karen Seto of Yale University. Cities are now organised into different compartments with distinct functions. Their main role is to ensure traveling between areas of residence, work areas, shopping centres and carparks. Since the 1960’s, major national reforms on land use planning have continued to transform the urban territory, precipitating the expansion of cities and the disappearance of natural peri-urban areas. The Sainte-Victoire mountain, an emblematic and meaningful place, whose pictorial motif constitutes a common heritage asset known to all, continues to disappear from the urban landscape of Aix-en-Provence. The Pays d'Aix’s strong economic development is ​​at the origin of significant land pressure driven by colossal financial stake which contribute to damaging this territory. Here, perhaps more than elsewhere, the question of city-country relations arises.
