The creation of the Cité de l’Économie et de la Monnaie already involves a large number of players. The Banque de France project team is working together with two high-level bodies chaired by Marc-Olivier Strauss-Kahn: the steering committee and the scientific council. It also receives contributions from specialized working groups: project content, practical implementation or ad-hoc themes. Specific bodies, such as the competition jury, also played a key role. This section presents some of these players.
