The term “Vivarium”, refers to an enclosure designed for observing living organisms under controlled, semi-natural conditions. The project adopts this terminology in order to conceptualize exhibition space not as an enclosed gallery environment, but as an open spatial system in which natural processes become integral components of curatorial experience. Thus, the Vivarium Open-Air Exhibition proposes an alternative exhibition framework in which the integration of landscape elements mediates the relationship between spatial perception and curated content. Through the controlled manipulation of light, circulation, and vegetation, both two-dimensional and three-dimensional materials are situated within a shared environmental setting. Rather than positioning nature as a passive backdrop to displayed artefacts, the intervention foregrounds the landscape itself as an active exhibition medium. A sequence of interconnected platforms enables users to observe exhibited works, environmental conditions, and one another within a collectively shared spatial field. By enhancing existing open space through environmental integration, the project operates as a performative exhibition ground where perception, movement, and interaction become central components of the curatorial experience.
