The four corner towers of the new Biblioteque Nationale
de France (BnF) resemble four open books. These four
"books" plus the underground floors contain altogether
400 km of shelves for 20 million books. According to
the architect Dominique Perrault one of the inspirational
concept when designing the library was a typical medieval
cluster. This idea is in part achieved by the fantastic winter
garden that stand surrounded by the four towers in the
middle of this gigantic but also minimalistic complex.
All the best.
