The Atrium is the meeting place in the City Hall for citizens of The Hague and visitors/tourists to The Hague.

Cultural, educational, social and commercial exhibitions and events are organized. The Atrium City Hall foundation has been organizing these various activities in the Atrium since the opening of the City Hall in September 1995. The foundation does this on her own initiative, but external parties can also rent the space for an event or exhibition. In this way Atrium City Hall provides a varied picture of what is happening in The Hague and far beyond.
