Underground Megastructures [1/5]: "816 Nuclear Military Plant is an unfinished Chinese underground nuclear weapons production facility and the largest man-made tunnel structure in the world.[1] A military megaproject, the nuclear base is located near what is now suburban Fuling, a municipality in Chongqing, China. In 2010, it was opened to Chinese tourists. The surface area of the cave is more than 104,000 square metres, and the total length of the tunnels is more than 20 kilometers. The whole complex consists of 13 levels, 18 artificial caves linked to each other, and has more than 80 roads and 130 tunnels. Automobiles are able to pass the roads and tunnels inside. The base has the “World's Largest Artificial Cave”, which has a height of 79.6 meters, roughly equal to that of a 20-floor building." [1] https://en.wikipedia.org/wiki/816_Nuclear_Military_Plant

Underground Megastructures [2/5]: "Beijing's Underground City. The tunnels, built from 1969 to 1979 by more than 300,000 local citizens and even school children, wind for over 30 kilometers and cover an area of 85 square kilometers eight to eighteen meters under the surface. It includes around a thousand anti-air raid structures. In the event of attack, the plan was to house forty percent of the capital’s population underground and for the remainder to move to neighboring hills. There is no authoritative information on how far the mostly hand-dug tunnels stretch, but they supposedly link all areas of central Beijing, from Xidan and Xuanwumen to Qianmen and Chongwen districts, to as far as the Western Hills. They were equipped with facilities such as stores, restaurants, clinics, schools, theaters, reading rooms, factories, a roller skating rink, a grain and oil warehouse as well as barber shops and a mushroom cultivation farm, for growing foods that require little light."

Underground Megastructures [3/5]: "The Moscow Metro. Metro-2 is the informal designation for a clandestine and officially unacknowledged deep underground metro system in the Moscow metropolitan area. // These facilities are interconnected by a network of deep subway lines that provide a quick and secure means of evacuation for the leadership and are intended for the national command authority in wartime. They are estimated to be between 200 m (660 ft) and 300 m (980 ft) deep, and can accommodate an estimated 10,000 people. A special subway line runs from some points in Moscow and possibly to the VIP terminal at Vnukovo Airfield" [1] https://en.wikipedia.org/wiki/Metro-2

Underground Megastructures [4/5]: "The Kőbánya cellar system is an extensive network of subterranean, or underground spaces, in the 10th district of Budapest (Kőbánya), in Hungary. It is considered to be the largest cellar complex in the country. The floor area of the complex is variously estimated to be somewhere between 180,000–220,000 m2 (1,900,000–2,400,000 sq ft; 44–54 acres) and the combined length of the tunnels is estimated to be around 32–35 km (20–22 mi). Corridors 3–6 m (9.8–19.7 ft) wide and halls 10 m (33 ft) high are common in it. The deepest part is approximately 30 m (98 ft) under the ground surface."

Underground Megastructures [5/5]: "The Shanghai Complex. China's largest metropolis has completed building a vast bunker in case of explosions, emissions of poisonous gas or nuclear radiation. The complex covers 90,000 square meters and can accomodate 200,000 people, according to the Shanghai Morning Post. The underground haven has 15 passages nearly 2.5 miles (4km) in length that link to office towers and residential apartments. It is also connected to the subway system, enabling people to flee from one district to another. Water, power and ventilation systems can support the bunker's population for between seven and fifteen days. In times of peace, some parts can be used as garages, warehouses or commercial facilities." [1] https://www.chinadaily.com.cn/china/2006-07/31/content_653317.htm
