The Heritage Ballroom at the Fullerton Hotel Sydney is a 400-square-metre, pillarless function space within the former General Post Office building at 1 Martin Place. Its striking 11-metre domed ceiling, Victorian detailing and natural light distinguish it from the hotel's modern Grand Ballroom. The operator specifies 350 in theatre format, 250 banquet and 160 classroom; an adjoining foyer can be used for registration or drinks. This is a premium venue for dinners, business presentations and corporate celebrations. Catering, event production, equipment and final configurations require an individual hotel quotation.
