Physical context refers to the immediate surroundings of an artwork, including its location, how viewers access and experience it, and how it functions in that space. Historical context considers when and where a work was created and the social, political, and artistic climate of that time period. Cultural context examines an artwork's conceptual role in the society where it was made, including how art functions in that culture and what the work reveals about that culture. These three types of context - physical, historical, and cultural - provide different but important lenses for understanding and interpreting artworks, such as Richard Serra's 1981 sculpture Tilted Arc located in New York City's Federal Plaza.
