A ring-shaped art installation is a type of public art or sculpture that is designed in the shape of a circle or ring. These installations often incorporate various materials and elements to create a visually striking and interactive piece. They can be found in parks, public squares, museums, and other cultural venues. Some well-known examples include the 'Circle of Life' at the entrance to the Kruger National Park in South Africa and the 'Ring of Fire' in New York City's Madison Square Park.
