How Did They Do That?
A marvel of ancient engineering, these water systems have become icons of an empire
The mighty Roman aqueduct is put under the microscope
Water is the life source of civilisation. Today, we have sophisticated systems to collect, store and channel fresh drinking water, but ancient societies had only limited technologies to keep people in their cities well-quenched. Though evidence of such engineering can be found across the ancient world, none compare to that invented by the Romans: the aqueduct. This system used gravity to carry water huge distances from its source, through a network of downward sloping tunnels and bridges. An incredible feat of engineering, it was only recently that this technology was surpassed.
