The Great Pyramid of Giza is the oldest monument on the list of the Seven Wonders of the Ancient World. It is also the only one left standing. It is a marvel of human engineering and construction, and its sheer size and scale rivals any structure built within the last few hundred years.

It’s construction, though, has always been the subject of much debate among scholars, because of its massive size and near perfect proportions.

Some evidence and theories suggest that 20,000 workers over the course of 20 years built it, and were even paid to do so. This would have required a great deal of organization and manpower in the way of accounting and record keeping. The Egyptians were known for their excellent documentation.

The pyramid was constructed out of stone blocks, each weighing at least 2 tons. There are theories suggesting that multiple men together maneuvered each block over a ramp that encircled the structure as it rose, or that they moved each stone up long ramps that got higher and longer as the pyramid got taller, or even that scaffolding was used. Many eschew each of these theories for different reasons, including the idea that wood that could have been used for scaffolding or ramps would have been at a premium, and using mud brick for those purposes would not have held under the enormous weight of each massive block. And, of course, there are the ideas that aliens built the pyramids. However the pyramid was constructed, it is a marvelous feat, and should be awed and respected, especially because it is standing today with relatively minor damage.

I travelled in Egypt in 2008 and visited many of the amazing landmarks the country boasts.  Read about my tour to the the Great Pyramid of Giza here:  Tombs, Temples & Treasure
