Which city is known for a radial plan that often incorporates circular avenues?

The city recognized for its radial plan that includes circular avenues is Paris. This urban layout can be traced back to the design philosophies of Georges-Eugène Haussmann in the mid-19th century. Haussmann’s renovations transformed Paris into a modern city, characterized by wide boulevards that radiate from key central points like the Arc de Triomphe. This geometric arrangement facilitates movement and promotes accessibility, aligning with the principles of a radial city plan.

While other cities also exhibit radial characteristics—such as Washington D.C., with its arrangement of streets emanating from prominent landmarks like the Capitol—Paris is most famously associated with this style due to its historic significance and the distinctiveness of Haussmann's vision, setting it apart from the other options listed.
