Architectural Wonders Of The Ancient World: The Pyramids – Egypt
No list of architectural wonders of the ancient world would be complete without a mention of the famous Pyramids in Egypt. The Pyramid of Djoser, the oldest of the Pyramids, is estimated to have been built around the year 2630 B.C. Still today, experts have not been able to come up with a solid conclusion to explain how the ancient Egyptians built these perfectly aligned buildings using nothing but physical strength. It is presumed that as many as 100,000 slaves worked over the years to build these immense, mysterious tombs, which are still considered one of the Seven Wonders of the World.
