Private mansion located at 12 rue Colbert and 58 bis rue de Richelieu, in the 2nd arrondissement of Paris, the Nevers hotel now belongs to the National Library of France.
From the 144-meter long main wing, there remains today only a modest remnant inscribed in the Historical Monuments. Property of Cardinal Mazarin in the seventeenth century, the hotel Nevers is divided into two lots at his death. The part that we know today comes back to his nephew, Philippe Mancini, Duke of Nevers. Over the years, it will be seriously reduced due to financial problems.
In the first half of the 18th century, the hotel hosted the Royal Library on the orders of Louis XV. At the end of the century, however, it will be destroyed because of new developments.
