PUBLIC ART encompasses any work of art that an artist has created to be displayed, heard or performed in a public space. Although the oldest and most common forms of public art are monuments, memorials and statues, contemporary public art comprises a wide range of methodologies, forms and content. Public art ranges in scope from large-scale, commissioned works, which require significant collaboration amongst artists, funders and governmental agencies to implement, to independently executed small-scale works that require little to no funding. Public artworks may be site-specific, exhibited in non-conventional spaces or may alter the common function of a space. Approaches to contemporary public art include interactive art, guerilla art, sound art, community-based projects, and performance.
