The building’s architecture reflects the
“open space” concept in Bonn’s Haus der
Geschichte. Three barrel vaults, covered
entirely in glass, form the main design
element and supply the exhibition
rooms with daylight.
The glass elements contain two prism
systems. Sun protection prisms regulate
the indoor atmosphere, preventing the
rooms from heating up – even on hot
days. Deflection prisms ensure evenly
distributed, glare free illumination. The
effect is light flooded interiors with a
pleasant temperature, and perfect illu-
mination of the exhibits from all sides.
