Land art is a style of art that involves sculpting or making the land itself part of the installation. It’s either built out straight into the landscape or by assembling art structures in the landscape with natural objects or materials like boulders, twigs, or rocks.
Land art is sometimes known as Earth art and is often documented as maps or photographs that artists can exhibit online or in art galleries. It was considered part of the larger conceptual art movement in the 1960-1970s. Best-known land artists include Dennis Oppenheim, Michael Heizer, Walter de Maria, Robert Smithson, and Richard Long.
