The Fourth Plinth is a public art installation located in Trafalgar Square, London. It was originally intended to hold a statue of a horse and rider, but the statue was never completed. Since 1999, the plinth has been used to showcase a rotating series of contemporary artworks, allowing artists to present their work to the public. Each artwork displayed on the Fourth Plinth is selected through a competitive process, highlighting diverse themes and ideas. This initiative aims to engage the public in discussions about art and its role in society, making the plinth a dynamic part of London's cultural landscape.
