Les Halles was Paris' central fresh food market. It last operated on 12 January 1973 and was replaced by an underground shopping centre and a park. The unpopular modernist development was demolished yet again in 2010, and replaced by the Westfield Forum des Halles, a modern shopping mall built largely underground and topped by an undulating 2.5 hectare canopy. The mall sees around 50 million visitors every year, making it the busiest in France as of 2019. It is directly connected to the massive RER and métro transit hub of Châtelet–Les Halles, Paris's busiest station.

Paris is the capital and most populous city of France. With an official estimated population of 2,102,650 residents as of 1 January 2023 in an area of more than 105 km2 (41 sq mi), Paris is the fourth-most populated city in the European Union and the 30th most densely populated city in the world in 2022. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, culture, fashion, and gastronomy. For its leading role in the arts and sciences, as well as its early and extensive system of street lighting, in the 19th century, it became known as the City of Light.
