8. Giza Pyramids, Egypt
The grandeur of the Giza Pyramids is mind-blowing when you consider the minimal technology that would have been available around 2560 BC, when the Great Pyramid is thought to have been built. The Great Pyramid, which is the oldest, largest and most famous pyramid, is the last of the ancient world’s seven wonders still standing which is impressive on its own. Exactly how the Egyptians built these colossal structures is still a matter of debate today.
