This term refers to any artistic performance or artefact that is intended for reception by and/or creative participation of the public at large, often outside of the traditional spaces, and modes, in which art is engaged with (concert hall, gallery etc.). It may take any one of a number of possible forms (performance, installation, intervention, sculpture etc.) and is not necessarily intended to be appreciated by a traditional or expert audience associated with any one form of artistic practice. Public art can be incorporated as an aspect of urban and regional planning, through the commissioning of performances and artefacts associated with the animation, energising or redevelopment of specific sites or areas.
