How could ancient civilisations have built huge structures in less time than it takes to construct the biggest buildings of today? Could Ancient Egyptians have produced thousands of chariots with assembly-line precision? Why would the Romans have created a massive underground industrial hell, where thousands of slaves never saw daylight? Ancient Impossible s1e8: Biggest Builds
One of the Romans’ most incredible inventions was concrete. ibid.
Caesarea: The harbour was an engineering marvel – over a million cubic feet of contrete embedded in the sea. ibid.
Barbegal, France: A water-powered factory. ibid.
The hellish mechanised world that kept the Roman Empire in silver. An unbelievable system of slave-powered water-wheels deep inside the earth. ibid.
Roman arenas: engineering triumphs, built to house gladiators fighting to their deaths. The Romans also created a mobile and deadly armoured weapon likened to the tank. This ancient empire even built a massive wall straight across Britain in unbelievably short time. Ancient Impossible s1e9: Roman Empire
The Colosseum: All around the area are arches that both support the structure and provide access to every seat. This design is so effective it has yet to be improved upon. ibid.
The end of the empire was this frontier – Hadrian’s Wall – 73 miles long … in just five years. ibid.
Rome created snipers, repeating weapons and artillery barages to build an empire. ibid.
The Ballista wasn’t just powerful, it was accurate. ibid.
The Roman army had fully armoured horses. ibid.
Might the Ancient Egyptians have created a giant circular saw that could cut through granite? Julius Caesar it seems built a bridge across the Rhine in just 10 days and marched his Roman army of 40,000 over it. Then there are the secrets of the greatest harbour of the ancient world. Ancient Impossible s1e10: Extreme Engineering
Pharos, the Great Lighthouse of Alexandria: 400 feet high … the equivalent of a 40-storey building. ibid.
