The Aula of the Technical University in Delft located on the north side of the campus was built from 1959 to 1966 by the Dutch practice Van den Broek & Bakema. The building houses an auditorium with 1300 seats, four trapezoid lecture halls with 250 to 350 seats, the senate hall and the university cafeteria.

The auditorium
The auditorium looms above the main entrance. It is the largest room in the Aula Congress centre, with more than 1000 seats, meets the most modern and diverse wishes to turn this symposium into a real experience. Advanced digital light, image and sound system, videoconferencing and Internet broadcast equipment make the Auditorium utmost suitable for Multimedia and Richmedia applications.

The hall
The hall is shaped like a saucer (hence the building's nickname "the UFO") and is supported by triangular concrete columns. The lecture halls at the rear are supported by a similar construction. To support the 15 metre overhang prestressed concrete had to be used. The ends of the prestressing cables are left exposed. The building has a collapsed roof. Steel frames were used for the exterior walls.

The Aula of the Technical University is the perfect location for the symposium as architectural and structural influences can be found throughout the whole building.
