The National Library is located on a hill overlooking the historical city center of Prague. It serves both as a national archive and as a public library. The building is conceived as a cantilevered spiral tower. The enclosed archive departments form a continuous building volume that winds up around a central void space. The counter form of this enclosed volume is a transparent spiral deck that is formed by the roof of these archives. This deck becomes one giant spiral staircase for the public library areas of the building. The spiral culminates in a panoramic roof terrace, overlooking the city of Prague.
