Immense and majestic, the four towers of the François Mitterrand National Library dominate the urban landscape of the 12th and 13th arrondissements. We explain their history.

The towers of the Bibliothèque nationale de France(François Mitterrand site) can be seen from the Seine during a stroll through the Parc de Bercy, overlooking the library's premises. Opened to the public in 1996, the site became the first building to use wire cloth as interior decoration.

Designed byarchitect Dominique Perrault, the BnF is made up of four glass towers, the four "Bnf towers" in the shape of open books. Each tower is placed on one of the corners of the esplanade, giving the building a cubic appearance and a reference to the national library. Each tower reaches a height of 79 metres, and each has a name: the tower of time, the tower of laws, the tower of numbers and the tower of letters.
