10. Great Wall of China – The Longest Man-Made Structure on Earth
Stretching over 13,000 miles (21,000 km), the Great Wall of China is not just one structure, but a vast network of walls, watchtowers, and fortifications built over many centuries. The earliest walls date back to the 7th century BC, but the most well-known sections were built during the Ming Dynasty (1368–1644) to protect China from northern invasions.
Made from a mix of stone, brick, tamped earth, and wood, the wall traverses mountains, deserts, and grasslands — some sections remain remarkably well-preserved, while others have crumbled into ruins. Its construction required immense manpower and resources, with laborers working under extreme conditions to shape this defensive marvel.
Why it’s impressive:
- The largest man-made military structure ever built
- Visible from space (under ideal conditions), though that claim is often exaggerated
- A symbol of China’s historical resilience and strategic ingenuity
Visiting tips:
- The Mutianyu and Jinshanling sections are less crowded than Badaling
- Best visited in spring or autumn for pleasant weather and clearer skies
Pro tip:
- Wear sturdy shoes — many parts of the wall involve steep, uneven stairs that can be physically demanding but rewarding.

7. Great Pyramid of Giza – Ancient Engineering Without Equal
The Great Pyramid of Giza is one of the most awe-inspiring feats of ancient engineering. Constructed around 2560 BC during the reign of Pharaoh Khufu, this structure was originally 481 feet (146.6 meters) tall and remained the tallest human-made structure on Earth for over 3,800 years. It is the only surviving wonder of the original Seven Wonders of the Ancient World.
The pyramid is composed of over 2 million limestone blocks, each weighing between 2.5 to 15 tons. Scholars still debate how the ancient Egyptians managed to transport and position these massive stones with such precision — without the use of modern machinery. The interior includes narrow passageways, chambers, and shafts aligned with incredible astronomical accuracy.
Why it’s impressive:
- Built without wheels, pulleys, or iron tools
- Aligns almost perfectly with the cardinal points (north, south, east, west)
- Its base is level within just a few centimeters across all four sides
Travel tip:
Located just outside Cairo, the Giza Plateau also houses the Sphinx and smaller pyramids — best visited early in the day to avoid heat and crowds.
