Black room
Part of a communications center used by state officials for surveillance
A black room is part of a communication center used by state officials to conduct clandestine interception and surveillance of communications. Typically, all letters or communications pass through the black room before being passed to the recipient. This practice had been in vogue since the establishment of postal and telegraph services, and was frequently used in France by the ministers of Louis XVIII and his followers as the cabinet noir.
