Final answer:
The capital city of France is Paris. It is a major urban center that has historically been the core of France's nationhood and is a primatial city with a population of nearly 11 million.
Step-by-step explanation:
The capital city of France is Paris. It has been the heart of French nationhood since it was made the capital in the 13th century during the time when Sainte-Chapelle was built. Today, Paris is not only a historical and cultural hub but also a predominant urban center favorably situated within France. It serves the surrounding regions, providing economic and administrative functions.
Paris underwent significant transformation in the nineteenth century under Baron Haussmann, which modernized the city. Moreover, it is now France's primate city, with a population of nearly 11 million, out of France's total of about 63 million as of 2017. This compares to the next largest city, Lyon, which has a population of about 1.6 million. Despite its size, Paris manages to be at the core of France's agricultural success, leading Europe in production.
