Site-Specific or Environmental Art is an art form, particularly known from the 1960s, in which the artist creates a three-dimensional space that involves the spectators and is often involved with several sensory stimulations, such as visual, auditory, kinetic, tactile, and sometimes olfactory. Environments can be in the nature of assemblage including figures made by the artist or objects of everyday life, or transformations of the natural landscape Another form of environmental art includes the earthworks form which integrates the artwork into the physical terrain (Land Art). Materials such as rocks, sticks, soil, plants and so on are often used, and the works frequently exist in the open and are left to change and erode under natural conditions. The Guggleheim Museum defines Site-specific or Environmental art as "an artist's intervention in a specific locale, creating a work that is integrated with its surroundings and that explores its relationship to the topography of its locale, whether indoors or out, urban, desert, marine, or otherwise. - The term also applies to an environmental installation or sculpture created especially for a particular gallery space or public site." " Environmental art is grounded in an ethos that focuses on interrelationships. These relationships include not only physical and biological pathways but also the cultural, political and historical aspects of ecological systems."
