Les Halles de Paris, usually simply Les Halles (French pronunciation: [le al], The Halls), was the name given to Paris's central fresh food market. Located in the heart of the city, it was demolished in 1971 and replaced with the 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.
Since 2010, a major reconstruction of the mall is under progress. The new version is planned to be inaugurated by 2016. The mall remains open during works. In 2013, the Forum des Halles was still the second most visited shopping mall in France with 39.2 million visitors.(Wikipedia)
