21st Century Museum of Contemporary Art, Kanazawa 金沢21世紀美術館

The Kanazawa 21st Century Museum of Contemporary Art features a permanent exhibit called "The Swimming Pool." This artwork, created by Leandro Erlich in 2004, uses concrete, glass, and water. It creates an illusion of a deep pool, but visitors can actually enter the space beneath a shallow layer of water and glass.
