The Philological Library is the newest component on the campus of the Free University of Berlin. This library by Foster and Partners, built in 2005, is known as the Berlin Brain. Norman Foster sheltered the stacks of the university library with a double-layered canopy that opens for natural ventilation.
The library has become the centerpiece of the university's Dahlem campus and a Berlin architectural landmark. It holds 700,000 volumes.
The structure can be seen silhouetted on the canopy. The canopy's glowing, flowing panels inspire movement-driven floorplan. The overall blob shape results from an overall sense of place and movement. This movement culminates a yellow epicenter, a passageway to the next building. This building is about collective movement and transitions.
