Drafted by Sir Norman Foster the modern roof construction has become reality. A cupola made from glass and steel, about 23 m high and 40 m wide, provides the inner building with light and fresh air and also includes a walkway for visitors. Waagner Biró AG, Vienna has been in charge of execution. State-of-the art corrosion protection with hot dip galvanizing has been provided by Brunner Verzinkerei Brüder Bablik GmbH.
