Kongresshalle, Convention center in Tiergarten, Berlin, Germany

Kongresshalle is a convention center on John-Foster-Dulles-Allee in the Großer Tiergarten, Berlin. Its roof is a net of steel cables suspended from two steel arches and covered with concrete, spanning the auditorium that seats around 1,000 people. Below the sloping auditorium is a high foyer lit by a continuous band of windows. A rectangular reflecting pool with fountains lies on the street side.

Hugh Stubbins designed the building as an American contribution to the 1957 International Building Exhibition in post-war West Berlin. The roof collapsed in 1980 and was rebuilt with a modified structure by 1987.

Since 1989 the building has housed the Haus der Kulturen der Welt, which the Foreign Office funds as one of its five intermediary organisations for foreign cultural policy. The programme centres on contemporary arts and non-European cultures. Inside, a bar and a garden are named after Magnus Hirschfeld and Lili Elbe, recalling the sexology institute that stood on the site before the war.

Access is via John Foster Dulles Allee between the main station and Brandenburg Gate, with bus stops directly in front of the entrance. The spaces can be used for events, with opening hours depending on current exhibitions and programs.

The roof is a net of steel cables suspended from two steel arches and covered with concrete, a principle Stubbins's engineer Fred Severud had used for the Dorton Arena in Raleigh. The roof terrace measures 92 by 96 metres and was the original main entrance. A bronze by Henry Moore, Large Divided Oval: Butterfly, stands in the mirror pond since 1987.
