The City of Melbourne manages an Art and Heritage Collection comprising both objects and artworks (indoor and outdoor). The outdoor component of the Collection includes around 150 artworks, while the indoor element is made up of approximately 6000 historical and contemporary objects including civic and ceremonial objects, commemorative objects, sister city gifts, architectural drawings, streetscape images of Melbourne as well as a contemporary art collection. The Collection is used predominantly by researchers as well as by the City Gallery, located on the ground level at the Melbourne Town Hall, which draws upon the Collection for its annual program of five contemporary art and social history exhibitions. An Acquisitions Panel continues to acquire contemporary art with a particular focus on indigenous artwork. Many of the artworks acquired by the council are displayed within the Melbourne Town Hall.
