Taking that as a proxy for building a wall, and 75 feet as roughly 25 meters = 1 meter per day, 21196 kilometers = 21196000 meters = 21196000 days = 58,000 years.
How Long Would It Take to Build the Great Wall of China Today?
The Great Wall of China is one of the world’s most iconic ancient structures, stretching over 6,000 kilometers and built over hundreds of years. The Great Wall was originally constructed over two millennia ago, and its purpose was to protect the Chinese empire from barbarian invasions. Despite its age, the wall is still largely intact and remains an impressive feat of engineering. But if it were to be built today, how long would it take?
The answer depends on the size, scale, and materials used to build the wall. Estimates of the time it would take to build the Great Wall of China today range anywhere from 15 to 30 years. This is based on the assumption that the wall would be built with modern building materials and methods, including reinforced concrete and steel.
The cost of constructing the Great Wall of China today would also be much higher than it was when it was originally built. The cost of labor and building materials has increased significantly over the last two millennia, and the wall would likely require a significant investment of capital.
In addition to the cost and time required to build the Great Wall of China, there are also logistical considerations. Construction would need to be coordinated across vast distances and the availability of the resources needed for construction would
