A convention center (American English, conference centre outside the USA and Canada) is a large building that is designed to hold a convention, where individuals and groups gather to promote and share common interests. Convention centers typically offer sufficient floor area to accommodate several thousand attendees. Very large venues, suitable for major trade shows, are sometimes known as 'exhibition centres'. Convention centers typically have at least one auditorium and may also contain concert halls, lecture halls, meeting rooms, and conference rooms. Some large resort area hotels include a convention center.

Zaha Hadid, CBE (Arabic: زها حديد‎ Zahā Ḥadīd; born 31 October 1950) is an Iraqi-British architect and winner of the Pritzker Architecture Prize in 2004.

Hadid was born in 1950 in Baghdad, Iraq. She received a degree in mathematics from the American University of Beirut before moving to study at the Architectural Association School of Architecture in London.

After graduating she worked with her former teachers, Rem Koolhaas and Elia Zenghelis at the Office for Metropolitan Architecture, becoming a partner in 1977. It was with Koolhaas that she met the engineer Peter Rice who gave her support and encouragement early on, at a time when her work seemed difficult to build. In 1980 she established her own London-based practice. During the 1980s she also taught at the Architectural Association. She has also taught at prestigious institutions around the world; she held the Kenzo Tange Chair at the Graduate School of Design, Harvard University, the Sullivan Chair at the University of Illinois at Chicago School of Architecture, guest professorships at the Hochschule für bildende Künste Hamburg, the Knowlton School of Architecture, at The Ohio State University, the Masters Studio at Columbia University, New York and the Eero Saarinen Visiting Professor of Architectural Design at the Yale School of Architecture in New Haven, Connecticut. In addition, she was made Honorary Member of the American Academy of Arts and Letters and an Honorary Fellow of the American Institute of Architects. She has been on the Board of Trustees of The Architecture Foundation. She is currently Professor at the University of Applied Arts Vienna in Austria.
