For thousands of years, people have been building homes, temples and monuments, but until only a few centuries ago, they had no proper plans to follow before building began. They based their work on tried and tested methods, estimating how strongly walls had to be built to support the floors above and the roof. Of course, many buildings collapsed or subsided, but others are still standing to this day, a tribute to the skill of builders in times past.
The last remaining of the Seven Wonders of the ancient world, the great pyramids of Giza are perhaps the most famous and discussed structures in history. These massive monuments were unsurpassed in height for thousands of years after their construction and continue to amaze and enthrall us with their overwhelming mass and seemingly impossible perfection. Their exacting orientation and mind-boggling construction has elicited many theories about their origins, including unsupported suggestions that they had extra-terrestrial impetus. However, by examining the several hundred years prior to their emergence on the Giza plateau, it becomes clear that these incredible structures were the result of many experiments, some more successful than others, and represent an apogee in the development of the royal mortuary complex.
