For the first time, the central axis was digitally duplicated with digital twin technology. In 2020, the Beijing Institute of Surveying and Mapping established a technical team of nearly 200 members to carry out ultra-fine surveying and 3D modeling for heritage elements along the central axis.
However, digital products can break through the limitations of time and space, allowing people to appreciate the unique charm of the central axis, Tao noted. The greatest feature of the Beijing Central Axis is that it has an undulating layout and maintains mirror symmetry on its east and west sides, said Tao Yingchun, director of the big data center of the Beijing Institute of Surveying and Mapping, adding that it is impossible for a visitor to get an overview of the entire central axis at any one heritage site. Today, with the rapid development of science and technology, the ancient central axis is better protected and inherited, blossoming with dazzling brilliance.Īs night fell, in front of the Yongding Gate, a vehicle equipped with a laser modeling system slowly drove by, meticulously measuring and recording details about the Beijing Central Axis roadway and neighboring structures.Īt daybreak, surveying and mapping engineers had already positioned equipment before a hall of the Temple of Agriculture, collecting statistics and portraying each facet. It connects many historical sites, including 3 World Heritage Sites and 11 major historical and cultural sites protected at the national level, which embody the great creativity and outstanding talent of the Chinese nation in urban planning and construction. The Imperial Ancestral Temple, the Altar of Land and Grain, the Temple of Heaven, and the Temple of Agriculture sit symmetrically in the west and east wings of the central axis.Īs the existing longest urban central axis in the world, it contains the essence of ancient architecture of Beijing, carries on the memorable moments of the Chinese civilization. It stretches from the Yongding Gate in the south of the city and the Drum Tower and Bell Tower in the north, crossing the Wanning Bridge, the Jingshan Mountain, the Palace Museum, the Duanmen Gate, the Tian'anmen Square and its adjacent areas, the Zhengyang Gate, and the street remains of the southern section of the central axis.
In Beijing, there is a north-south axis known as the Beijing Central Axis, or Zhongzhouxian, running through the city.įirst created in the Yuan Dynasty (1271-1368), the 7.8-kilometer central axis serves the function of a "book spine", forming a unique Beijing city pattern of bilateral symmetry and solemnity.
