What is the largest man-made structure on Earth?

The Burj Khalifa in Dubai is currently the tallest man-made structure in the world, standing at 828 meters (2,717 feet) tall. Completed in 2010, the Burj Khalifa is a skyscraper that features luxury residences, offices, and hotels.

However, if we are looking for the largest man-made structure by volume, the honor goes to the Great Wall of China. Spanning over 13,000 miles across China, the wall was built over many centuries, beginning in the 7th century BCE. While the wall is not a single continuous structure, its total volume makes it the largest man-made structure in the world.

Another massive man-made structure is the Three Gorges Dam in China, which is the world's largest power station in terms of installed capacity. Completed in 2012, the dam stands at 181 meters (594 feet) tall and spans over 2 miles in length, with a total installed capacity of 22,500 megawatts.

There are many other impressive man-made structures around the world, including the Palm Jumeirah in Dubai, the Panama Canal, and the Large Hadron Collider in Switzerland, but the Burj Khalifa, Great Wall of China, and Three Gorges Dam remain some of the largest and most iconic examples of human engineering and construction.
