Abstract : More than 20 years after the pyramid built by Ieoh Ming Pei in the Napoleon courtyard of the Louvre, which was inaugurated in 1989, and the annexation of the Richelieu wing, formerly occupied by the French Ministry of Finances, the Louvre has just been given a new extension. On the 18th of September 2012 indeed, President François Hollande officially opened the new department of Islamic Arts, of which the Louvre has one of the largest collections in the world.
