The world's largest map is known as the True Marble Earth, created by Xihe China. This map covers an area of approximately 48,664 square feet (4,522 square meters). It is an enormous physical map that is set on the ground at the Yancheng Coastal Wetlands in Jiangsu Province, China. The map is made up of 60 individual marble plates, each weighing around two tons. They are arranged to represent the continents and oceans of our planet. The True Marble Earth is an impressive example of a large-scale map that allows people to walk on its surface and explore the world in a unique way.
