The isolation of the gallery space from the world outside the museum reinforced the understanding that art belongs to the 'universal and eternal spiritual realm', with nothing to do with money or politics. The fewer the objects exhibited in modern museums and the more empty the walls, the more sacred the museum space becomes. In this context, the modern art museum, also called the white cube, is unspoiled and pure spaces designed to present art in a still and quiet environment, undisturbed by the intervention of people. This study was carried out with the literature review method. In today's art, it is aimed to be a resource that presents current examples to researchers working on the interaction of gallery space and nature, by creating works that focus on the relationship between the gallery space and nature.
