When the historic Les Halles building was demolished 1971 the market was moved to Rungis, 7 km outside of Paris. Then the 'Forum des Halles', a large shopping mall area, was erected on its place. It was first very popular but eventually became run down and disagreeable. In 2010 City Hall therefore decided to renovate the entire quartier. Now the prominent canopy was installed and the outlines of a curved huge glass roof is visible and heightens expectations.
During the immense construction the Metro and RER underground is still accessible and the different complicated accesses are endured by patient travelers. http://www.vinci-construction.com/en/project/20240/the-les-halles-redevelopment-project-in-paris
