Marseille
Seaside view of the Old Port of Marseille, France.
The limestone hills surrounding Marseille have significantly influenced the city’s urban development by acting as a restrictive natural barrier. Situated within a sheltered depression, the city is hemmed in by this semicircle of hills, which has historically inhibited the expansion of its suburbs.1234
This geographical constraint has forced the city’s growth to adapt in specific ways:
- Northward Limitation: The Étoile Chain of mountains serves as a major barrier to the north. Consequently, urban development has been forced to "leapfrog" this range, extending toward the eastern shores of the Berre Lagoon and into suburbs such as Marignane and Vitrolles.1
- Eastern Expansion: Due to the pressure of urban growth, the city’s boundaries have been pushed outward, particularly along the line of the Huveaune valley.1
While these hills limited outward sprawl, the sheltered natural harbor they created was the primary factor that allowed Marseille to establish itself as a major Mediterranean port.24
