Congress Centre Omar Bongo Ondimba

The Palace

A temple of memory and public speech, the Omar Bongo Ondimba Congress Centre is the diplomatic heart of Gabon.

The epic

Half a century of African history under one roof.

1977

The birth

President Omar Bongo built the Palace to host the 34th summit of the Organisation of African Unity. Libreville became a diplomatic crossroads of the continent.

1990–2014

Public speech

The 1990 National Conference, summits, congresses: the defining hours of Gabonese and African political life were written within these walls.

The eclipse

A decade of silence

The monument bided its time. The surrounding Cité de la Démocratie kept the memory of the great gatherings.

2026

The rebirth

Fully renovated, the Palace was inaugurated on 3 May 2026 by President Brice Clotaire Oligui Nguema before several heads of state. Radiance regained.

The architecture

A 3,100-seat Congress Hall, a Banquet Hall seating 1,600 to 2,200, a 350-seat auditorium, a presidential hall and some ten meeting rooms: a modern vessel built to international standards, at the heart of the Cité de la Démocratie.

The Cité & biodiversity

The Palace sits in a green setting unlike any other: Gabon is 88% forest cover, with forest elephants and gorillas less than an hour from the capital. Hosting an event in Libreville means gathering the world in the green lung of Africa.
