The World Forum was formerly the Nederlands Congres Centrum (NCC) and prior to that the Nederlands Congresgebouw (NCG). It was opened in 1969 and was designed in the Dutch functionalism style by architect Jacobus Johannes Pieter Oud. His son, Hans Oud, completed the construction after his father’s death in 1963.
The Nederlands Congresgebouw was extremely modern for the 1960s. A ceramic artwork by Karel Appel stemming from that era can still be seen on the exterior wall beside the entrance.
The former owner of the convention centre was the Municipality of The Hague and it sold the centre to TCN in 2001.
In October 2009, the French company GL events took over the operation of the World
Forum from the property developer TCN, and in July 2013 the City of The Hague regained ownership of the venue.
