Christo’s installations are also called landscape art or land art, right?

Land art is also called "landscape art".

It refers to an art form that is rich in artistic integrity and created by artists who use nature as a creative medium and organically combine art with nature. The first "local works art exhibition" was held in 1968 at the Duwang Gallery in New York, USA. This announced the emergence of a new modern art form - land art. Land art can be said to be the concrete practice of China’s Zhuangzi’s philosophy of “the unity of nature and man”. Land Artist believes that there should be no strict boundaries between art and life, art and nature. In human life time and space, art should exist everywhere. Land art can be seen as the result of the development of indoor decoration works to the outdoors. The earliest styles can be traced back to the pyramids of ancient Egypt and the Stonehenge circular stone columns in the UK. Land art works are all very concerned with the "sense of place" of the work, that is, the work is organically integrated with the environment, and the characteristics of the site itself such as topography, geology, seasonal changes, etc. are strengthened or weakened through design, thereby guiding people to experience nature more deeply. Robert Smithson also used sand and gravel to build a "spiral breakwater" with a diameter of 160 feet and a length of 1,500 feet on the Great Salt Lake in Utah, USA. The scene was grand and shocking. In addition, there are artists who love to use a hole drill to dig a hole deep enough in a certain place on the ground; or dig several large sand pits in a certain lawn; or create a sea and land landscape in an open space. "Parks"...etc., come in many forms. In China, at the end of 1994, the "Red Umbrella Incident" occurred in Tianjin, which caused a sensation in which tourists stole the devices and placed them in parks and other places. The "Red Umbrella Landscape" consisting of tens of thousands of red umbrellas installed in parks and other places is a living work of land art. From the broad perspective of land art, the Great Wall of China is a magnificent, spectacular and immortal "land art" work collectively created by the ancient Chinese people. Good luck!
