The sculpture created by Robert Irwin is located at the highest point of the visiting area of the Inhotim Institute. The artist based his work on an architectural language present in constructions made from prefabricated concrete molds. The sloping walls form an octagonal structure that houses, at the top of each wall, triangular, textured yellow glass panels.
The incidence of sunlight, which varies throughout the day, penetrates the sculpture, which is open to the sky and partially unfolded, creating plays of light and shadow on the floor and walls of the sculpture. Thus, the work highlights the perception not only of its formal structure, but also of the natural phenomena to which it is subject.
