two of the highest buildings in Paris at the time, the Tour Eiffel and the Tour Montparnasse. The two sides of the Arche house government offices. The roof section was closed in 2010 following an accident without injury and the marble tiles which had begun to peel off were replaced with granite ones. It opened again in 2017 after seven years of renovation work. It features panoramic views of Paris and includes a restaurant and an exhibition area dedicated to photojournalism. The void contains skeletal shafts for panoramic lifts and a PTFE-and-fibreglass tensile-membrane sunshade known as the "Cloud" (Le nuage). Gallery Tenants Organizations headquartered in the Grande Arche include the Bureau d'Enquêtes sur les Événements de Mer (BEAmer), the French marine accident investigation agency, in the southern portion.
