Les Halles (French pronunciation: ​[le al]; 'The Halls') was Paris' central fresh food market. It last operated on 12 January 1973, after which it was "left to the demolition men who will knock down the last three of the eight iron-and-glass pavilions" and replaced by an underground shopping centre. The hugely unsuccessful and unpopular 1960s modern development together with the unattractive 1980s modern garden on top of it, was demolished yet again in 2010, and replaced by the Westfield Forum des Halles, a modern shopping mall built largely underground and directly connected to the massive RER and métro transit hub of Châtelet–Les Halles. The shopping mall welcomes 150,000 visitors daily.

A major reconstruction of the mall was undertaken in 2010, and the new version of the Forum des Halles was inaugurated in 2018. The 2.5 hectare Canopy was opened on 5 April 2016. In 2017, the Forum des Halles was the second most visited shopping mall in the Paris region with 42 million yearly visitors.
