This is just a few examples of great architecture and engineering, there are many more.
The Pantheon was built without modern machines or tools
It is remarkable that The Pantheon even today, nearly two thousand years after it was constructed, is as stable as when it was first built. It is almost beyond understanding that the Romans could build this structure without the benefit of modern machines or tools. Nor did the Pantheon engineers have the advantage of modern transportation methods. All the materials were floated down the Tiber and moved to the site by man and animal on carts of the period.
Almost no restoration
Though its enormous bronze doors have been restored many times, no major structural work has ever had to be undertaken. This is all the more remarkable given the marshy land on which the structure is
