Hadrian (r. A.D. 117-138) was a Roman emperor known for his many building projects, cities named Hadrianopolis (Adrianopolis) after him, and the famous wall across Britain, from Tyne to Solway, designed to keep the barbarians out of Roman Britain (see map of Roman Britain).
The construction of a water supply system for the city (then still called Byzantium) had begun already under the Roman emperor Hadrian. Under Constantine I, when the city was rebuilt and increased in size, the system needed to be greatly expanded to meet the needs of the rapidly growing population.
